[0030] The embodiments of the present disclosure provide a method for processing media content, which will be described below in conjunction with specific embodiments.

[0031] Figure 1 The present invention provides a flow chart of a method for processing media content, which can be executed by a media content processing device, wherein the device can be implemented by software and / or hardware, and can generally be integrated in an electronic device. Figure 1 As shown, the method is applied to a first application, comprising:

[0032] Step 101: Acquire first media content, where the first media content is an image or a video.

[0033] The first media content may be the media content currently being processed, may be the media content acquired by the image acquisition module, or may be the media content opened locally, without limitation, and the first media content may be an image or a video. The media content processing method of the disclosed embodiment is applied to a first application, and the first application may be an application that supports the acquisition of media content and performs special effects processing, storage, work generation, and publishing on the media content, without limitation.

[0034] In some embodiments, the first application may obtain the first media content, and then may add a special effect object to the first media content in response to a special effect adding operation by the user, or may not perform other operations.

[0035] Step 102: In response to a local storage operation or a media content generation operation on the first media content, the image of the first media content is processed to embed special effect information to obtain second media content, and the second media content is stored.

[0036] Among them, the special effect information may be the relevant attribute information of the special effect included in the first media content. In the embodiment of the present disclosure, the special effect information may include at least one special effect identifier associated with the first media content, and a special effect identifier is used to represent a special effect object. The special effect object may be an element that can add special display effects to the media content. Different special effect objects have different functions. The embodiment of the present disclosure does not limit the specific special effect objects. For example, the special effect object may include at least one of a template, makeup, filter, special effect, sticker, text, etc. The second media content may be the first media content with special effect information added.

[0037] The special effect information is embedded in the form of a dark watermark. Watermark technology can be to embed some identification information as a watermark into a digital carrier such as media content, documents, software, or indirectly express it. A dark watermark can refer to a watermark that is hidden in the media content and difficult to see. The embodiment of the present disclosure embeds the special effect information into the first media content through the dark watermark technology. The dark watermark has the characteristics of being difficult to remove and robust, and can resist operations such as compression, cropping, painting, and rotation. By adding a dark watermark, the special effect information can be retained without affecting the picture effect of the media content.

[0038] After acquiring the first media content, the first application directly receives a local storage operation for the first media content, or receives a local storage operation for the first media content after adding a special effect object to the first media content, or receives a media content generation operation for the first media content, where the media content generation operation may be an operation for generating a multimedia work, and may embed at least one existing special effect information in the image of the first media content to obtain the second media content, and store the second media content locally or online. That is, when the first media content needs to be stored locally or a media work needs to be generated, the special effect information is embedded in the first media content to obtain the second media content.

[0039] In some embodiments, processing an image of the first media content to embed special effect information includes: processing the image of the first media content to embed multiple special effect information associated with the first media content, wherein the multiple special effect information is used to generate at least one associated special effect information of the first media content, and the at least one associated special effect information is displayed on an associated page of the first media content after release.

[0040] The associated special effect information may be information that specifically introduces at least one special effect object corresponding to the special effect information. The associated special effect information may include attribute information of at least one special effect object. The attribute information of the special effect object may include the above-mentioned special effect identification, special effect name and special effect icon, etc. The display form of the associated special effect information is not limited. For example, the associated special effect information may be displayed in the form of a card. The associated page may be a page that displays the specific details of the special effect information associated with the first media content. Through the associated page, the relevant content of each special effect object corresponding to the special effect information can be understood. For example, the associated page may be a special effect details page including special effect objects such as music and filters.

[0041] The first application processes the image of the first media content and may embed therein a plurality of special effect information associated with the first media content; subsequently, after the first media content is released, an associated page of the first media content may be displayed in response to a trigger operation, and at least one associated special effect information may be generated based on the special effect information of the first media content, and at least one associated special effect information may be displayed in the associated page. The specific display method is not limited, for example, at least one associated special effect information may be displayed in the form of a card.

[0042] For example, Figure 2 A schematic diagram of an associated page provided by an embodiment of the present disclosure, such as Figure 2 As shown, the figure shows an associated page 200, in which three associated special effect information can be displayed in the form of cards, specifically including card 201, card 202 and card 203, which correspond to three special effect objects, namely filter A, makeup B and sticker C, respectively. Each associated special effect information includes a special effect name and a special effect icon of a special effect object. Optionally, each associated special effect information can also include a trial component. The user can try out the special effect object corresponding to the associated special effect information by triggering the use component. The trial component in the figure is the "trial special effect" in the card. Figure 2 The associated pages and associated special effect information are only examples and are not limiting.

[0043] In the above scheme, by displaying the associated special effect information of the special effect information in the associated page of the published media content, the user can quickly use the corresponding special effect element based on the associated special effect information, which is helpful for the use and recommendation of the special effect information.

[0044] Step 103: Acquire third media content, wherein the third media content is obtained through an editing operation in the second application and / or a local editing operation.

[0045] The second application may be an application different from the first application, for example, the second application may be an application dedicated to editing media content. The editing operation and / or local editing operation in the second application includes at least one of the following: media content splicing operation, media content overlay operation, media content cropping operation, subtitle adding operation, and compression operation.

[0046] In some embodiments, the second media content also includes a special effect information field, wherein the special effect information field is destroyed after an editing operation in the second application and / or a local editing operation. The special effect information field may be one of the field information included in the second media content, the second media content may include multiple types of fields, and the special effect field information includes special effect information associated with the first media content. The special effect information field is generated by the first application and can be used in the first application, but will be destroyed after an editing operation in the second application and / or a local editing operation.

[0047] Step 104 : In response to the publishing operation on the third media content, the third media content is parsed to determine special effect information, and a special effect entry corresponding to the special effect information is displayed on the third media content.

[0048] The publishing operation can be understood as a user uploading media content to a media content platform, editing the publishing information of the media content, and then publishing it so that other users can see it. The special effect entrance can be understood as an entrance that can quickly enter the details page of the special effect object and use the special effect object. The presentation form of the special effect entrance can be set according to the actual situation. For example, the special effect entrance can be the special effect name of the special effect object.

[0049] After the first application obtains the third media content as described above, if it receives a publishing operation for the third media content, it can parse the third media content to determine the special effect information included therein. Specifically, it can use a transform domain watermark algorithm to extract a target watermark from the third media content, that is, convert the third media content into a transform domain image to read the target watermark therein, and read the special effect information in the target watermark. Then, after publishing the third media content, it displays the third media content, and displays a special effect entry corresponding to the special effect information on the third media content.

[0050] In some embodiments, when the special effect information includes multiple special effect identifiers, displaying the special effect entry corresponding to the special effect information on the third media content may include: determining the target special effect identifier based on the embedding time of the multiple special effect identifiers, and displaying the special effect name and / or special effect icon of the corresponding target special effect object on the third media content based on the target special effect identifier.

[0051] The embedding time can be understood as the specific time when the special effect identifier is added to the first media content. The embedding time of different special effect identifiers can be the same or different. The target special effect identifier can be the special effect identifier whose special effect entrance needs to be displayed among multiple special effect identifiers. The attribute information of a special effect object may include the above-mentioned special effect identifier, special effect name and special effect icon, etc. These attribute information can be used as the special effect entrance of the special effect object.

[0052] When the first application displays the special effect entry corresponding to the special effect information on the third media content, when the special effect information includes a special effect identifier, the special effect name and / or special effect icon of the special effect object corresponding to the special effect identifier can be directly displayed; and when the special effect information includes multiple special effect identifiers, a special effect identifier can be selected as the target special effect identifier according to the embedding time of each special effect identifier, and the specific selection method is not limited. For example, the special effect identifier with the earliest embedding time can be used as the target special effect identifier; then the special effect name and / or special effect icon of the target special effect object corresponding to the target special effect identifier can be displayed as the special effect entry on the third media content; the special effect name can be used as the special effect anchor point of the target special effect object, and then after receiving the trigger operation on the special effect entry, the special effect details page of the target special effect object can be displayed, and at least one associated special effect information corresponding to the special effect information can be displayed on the special effect details page, that is, multiple associated special effect information of multiple special effect objects corresponding to multiple special effect identifiers. The specific display position can be set, for example, in the top area, so that the user can use the above-mentioned multiple special effect objects on the special effect details page.

[0053] Optionally, determining a target special effect identifier based on the embedding time of multiple special effect identifiers may include: if the embedding time of multiple special effect identifiers is the same, determining the special effect identifier with the earliest parsing time among the multiple special effect identifiers as the target special effect identifier; otherwise, determining the special effect identifier with the latest embedding time among the multiple special effect identifiers as the target special effect identifier.

[0054] When determining the target special effect identifier, the first application can determine whether the embedding time of multiple special effect identifiers is the same. If so, the parsing time of each special effect identifier is compared. The parsing time of a special effect identifier indicates the specific time point when the special effect identifier is parsed when parsing the third media content. The special effect identifier with the earliest parsing time is determined as the target special effect identifier; if the embedding time of multiple special effect identifiers is different, the embedding time of each special effect identifier is compared, and the special effect identifier with the latest embedding time is determined as the target special effect identifier.

[0055] In the above scheme, when the special effect information includes a special effect identifier, the special effect entrance of the special effect object corresponding to the special effect identifier can be directly displayed on the third media content; when the special effect information includes multiple special effect identifiers, the target special effect identifier can be determined according to the embedding time and the special effect entrance of the target special effect object corresponding to the target special effect identifier can be displayed on the third media content, so that the display of the special effect entrance is more flexible, more in line with the actual needs of users, and helps to improve the recommendation and use efficiency of special effects.

[0056] The media content processing scheme provided by the disclosed embodiment is that the first application obtains the first media content, wherein the first media content is an image or a video; in response to a local storage operation or a media content generation operation on the first media content, the image of the first media content is processed to embed special effect information, thereby obtaining the second media content, and storing the second media content; obtaining the third media content, wherein the third media content is obtained through an editing operation and / or a local editing operation in the second application; in response to a publishing operation on the third media content, the third media content is parsed to determine the special effect information, and a special effect entry corresponding to the special effect information is displayed on the third media content. With the above technical scheme, the first application can embed the corresponding special effect information when storing or generating the media content, so that when the media content edited by the second application is subsequently obtained and then published, the special effect information can be parsed to obtain the special effect information and the corresponding special effect entry can be displayed. Since the special effect information is embedded in the media content, it is ensured that the special effect information will not be lost due to editing by other applications, thereby improving the security of the media content and facilitating the recommendation and use of related special effects.

[0057] In some embodiments, embedding special effect information into the first media content to obtain the second media content may include: using a transform domain watermark algorithm to convert the special effect information into a target watermark and embedding the target watermark into the first media content to obtain the second media content.

[0058] Among them, the transform domain watermark algorithm can be to convert the pixel information of the image to the transform domain, and then convert it to the spatial domain after adding information in the transform domain. In this process, the spatial domain information will also be modified, so the transform domain watermark can also be understood as an indirect spatial domain watermark. In the embodiment of the present disclosure, the transform domain watermark algorithm can include at least two of the discrete cosine transform domain watermark algorithm (Discrete Cosine Transform, DCT), discrete wavelet transform domain watermark algorithm (Discrete Wavelet Transformation, DWT), and discrete Fourier transform domain watermark algorithm (Discrete Fourier Transform, DFT). DCT can convert an image into a discrete cosine transform domain to achieve watermark embedding and extraction, DWT can convert an image into a discrete wavelet transform domain to achieve watermark embedding and extraction, and DFT can convert an image into a Fourier transform domain to achieve watermark embedding and extraction.

[0059] The first application can convert the first media content into a transform domain image through a transform domain watermark algorithm. The number of transform domain images is one or more. When the first media content is an image, it is converted into one transform domain image. When the first media content is a video, it is converted into multiple transform domain images. Then, the special effect information is encoded, and part of the pixel values ​​of the above transform domain image are modified into the encoded special effect information. The transform domain image with the special effect information is inversely transformed using the transform domain watermark algorithm to obtain a watermark image. The special effect information is converted into a target watermark through the above inverse transformation. The watermark image includes the target watermark. Then, the video synthesized by the watermark image or multiple watermark images is determined as the second media content.

[0060] In the above scheme, special effect information is embedded in the media content through the transform domain watermark algorithm. Due to the strong robustness of the transform domain watermark algorithm, under reasonable algorithm configuration, it can resist a certain degree of compression, noise, occlusion and other common attack methods, ensuring that the special effect information will not be lost due to editing, thereby improving the security of the media content.

[0061] In some embodiments, when the first media content is a video, embedding special effect information in the first media content to obtain the second media content may include: extracting at least one target image frame from the video; embedding special effect information in the at least one target image frame to obtain a watermark image frame, and synthesizing the second media content based on the at least one watermark image frame and other video frames in the video except the target image frame. Optionally, the target image frame is an image frame extracted from the video at a preset time interval or all image frames of the video.

[0062] The target image frame may be an image frame that is about to be embedded with special effect information, and the target image frame may be part of the image frame or all of the image frames included in the video. The watermark image frame may be an image frame that has been embedded with special effect information. The preset time interval may be a time interval for extracting image frames from the video as target image frames, which may be set according to actual conditions. For example, the preset time interval may be 4 seconds, and one frame of image may be extracted from the video every 4 seconds as the target image frame. For another example, the preset time interval may be set to the inverse of the frame rate of the video, and the frame rate may be the number of images refreshed per second in the video, so that all image frames of the video may be determined as target images.

[0063] When the first media content is a video, when the media content processing device embeds special effect information in the first media content, it can first extract image frames from the video, determine at least one extracted image frame as at least one target image frame, and then embed special effect information in each target image frame to obtain a corresponding watermark image frame, thereby obtaining at least one watermark image frame; synthesize at least one watermark image frame with other video frames in the video except the target image frame to obtain a new video, i.e., the second media content. By adding special effect information to at least one image frame of the video, the special effect information can be retained even if the image frame of the video is subsequently deleted, thereby improving the robustness of the special effect information.

[0064] In some embodiments, processing an image of a first media content to embed special effect information to obtain a second media content may include: for each special effect identifier, comparing the number of free bits in a preset field of the image of the first media content with the number of complete special effect identifier bits of the current special effect identifier to determine whether to add the special effect identifier.

[0065] When the first media content is an image, special effect information is embedded in the image, or when the first media content is a video, special effect information is embedded in each target image frame, that is, the image of the first media content is the target image frame, and each special effect identifier can be embedded in sequence; for each special effect identifier, before embedding, determine whether the image of the first media content supports adding the special effect identifier, specifically, the number of free bits of the preset field of the image of the first media content can be compared with the number of complete special effect identifier bits of the current special effect identifier, if it is determined that the number of free bits is greater than or equal to the number of complete special effect identifier bits of the current special effect identifier, if so, the embedding of the current special effect identifier is executed; otherwise, the embedding of the current special effect identifier is stopped. The preset field can refer to a specific field for adding special effect characters to an image, and the total number of bits of the preset field is the maximum number of characters supported by an image, for example, the total number of bits of the preset field can be 19. The number of free bits can be the number of free bits in the preset field to which characters have not yet been added. By determining whether the embedding of the complete special effect identifier is supported before embedding the special effect identifier, and stopping the embedding if it is not supported, the truncation of the special effect identifier and the corresponding to the wrong special effect object can be avoided, thereby improving the accuracy of embedding the special effect information and helping to improve the accuracy of subsequent use of the special effect objects.

[0066] Next, the embedding and extraction process of the special effect information as a watermark in the embodiment of the present disclosure will be described by taking the first media content as an image and the transform domain watermark algorithm including DWT and DCT as an example. Figure 3A schematic diagram of watermark embedding provided by an embodiment of the present disclosure, in which the original image is the above-mentioned first media content, and the original image is subjected to DWT transform and DCT transform to obtain a transform domain image; the special effect information is watermark encoded, and the specific encoding method may, for example, convert the special effect information into binary information, and modify part of the pixel values ​​in the transform domain image to the special effect information after the watermark encoding to achieve the embedding of the special effect information; the transform domain image embedded with the special effect information is subjected to inverse DCT transform and inverse DWT transform to obtain a watermark image with a target watermark added.

[0067] For example, Figure 4 A schematic diagram of watermark extraction provided by an embodiment of the present disclosure is provided. The watermark image is subjected to DWT transformation and DCT transformation to obtain a transform domain image. Hidden information is read from the transform domain image. The hidden information is the special effect information after the watermark is encoded. The hidden information is then watermark decoded and validity judged to obtain special effect information. The validity judgment here can be used to judge whether the special effect information after the watermark is decoded is correct, which can be achieved by self-checking.

[0068] In the disclosed embodiment, special effect information is embedded in the media content through a transform domain watermark algorithm. Since the transform domain watermark algorithm is highly robust, under reasonable algorithm configuration, it can resist a certain degree of common attack methods such as compression, noise, occlusion, etc., to ensure that the special effect information will not be lost due to editing, thereby improving the security of the media content.
