[0035] The embodiments of the present disclosure provide a method for processing media content, which will be described below in conjunction with specific embodiments.

[0036] FIG1 is a flow chart of a method for processing media content provided by an embodiment of the present disclosure. The method can be executed by a media content processing device, wherein the device can be implemented using software and / or hardware and can generally be integrated into an electronic device. As shown in FIG1 , the method is applied to a first application and includes:

[0037] Step 101: Acquire first media content, where the first media content is an image or a video.

[0038] The first media content may be media content currently being processed, media content acquired by an image acquisition module, or locally opened media content, without limitation. 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, which may be an application that supports acquiring media content and performing special effects processing, storage, creation of works, and publication of the media content, without limitation.

[0039] 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.

[0040] 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.

[0041] The special effects information may be attribute information related to the special effects included in the first media content. In the embodiment of the present disclosure, the special effects information may include at least one special effects identifier associated with the first media content, and a special effects identifier is used to represent a special effects object. A special effects object may be an element that can add special display effects to media content. Different special effects objects have different functions. The embodiment of the present disclosure does not limit the specific special effects objects. For example, a special effects 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 added special effects information.

[0042] Special effect information is embedded in the form of a dark watermark. Watermarking technology can be used to embed some identification information as a watermark into digital carriers such as media content, documents, and software, or indirectly represent it. A dark watermark can refer to a watermark that is hidden in the media content and difficult to see. The disclosed embodiment uses dark watermark technology to embed special effect information into the first media content. Dark watermarks have 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, special effect information can be retained without affecting the visual effect of the media content.

[0043] After acquiring the first media content, the first application may directly receive a local storage operation for the first media content, or receive a local storage operation for the first media content after adding a special effect object to the first media content, or receive 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. The first application may embed at least one existing special effect information into an image of the first media content to obtain second media content, and store the second media content locally or online. Specifically, 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.

[0044] In some embodiments, processing an image of the first media content to embed special effects information includes: processing the image of the first media content to embed multiple special effects information associated with the first media content, wherein the multiple special effects information are used to generate at least one associated special effects information of the first media content, and the at least one associated special effects information is displayed on an associated page of the first media content after publication.

[0045] 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 special effect identifier, special effect name, and special effect icon, etc. The display format 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 this 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.

[0046] The first application processes the image of the first media content and can embed multiple special effect information associated with the first media content therein; subsequently, after the first media content is released, the associated page of the first media content can be displayed in response to a trigger operation, and at least one associated special effect information can be generated based on the special effect information of the first media content, and the at least one associated special effect information can be displayed in the associated page. The specific display method is not limited, for example, at least one associated special effect information can be displayed in the form of a card.

[0047] Exemplarily, Figure 2 is a schematic diagram of an associated page provided by an embodiment of the present disclosure. As shown in Figure 2, an associated page 200 is shown in the figure. Three associated special effect information can be displayed in the form of cards in the associated page 200, specifically including card 201, card 202 and card 203, which correspond to three special effect objects: A filter, B makeup and C sticker, 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 the special effect object corresponding to the associated special effect information by triggering the usage component. The trial component in the figure is the "trial special effect" in the card. The associated pages and associated special effect information in Figure 2 are only examples and are not limiting.

[0048] In the above solution, by displaying the associated special effect information of the special effect information on the associated page of the published media content, the user can quickly use the corresponding special effect elements based on the associated special effect information, which is conducive to the use and recommendation of the special effect information.

[0049] Step 103: Acquire third media content, where the third media content is obtained through an editing operation in the second application and / or a local editing operation.

[0050] 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 operations and / or local editing operations in the second application include at least one of the following: media content splicing, media content overlaying, media content cropping, subtitle addition, and compression.

[0051] In some embodiments, the second media content also includes a special effects information field, wherein the special effects information field is destroyed after an editing operation in the second application and / or a local editing operation. The special effects information field can be one type of field information included in the second media content. The second media content can include multiple types of fields, and the special effects field information includes special effects information associated with the first media content. The special effects 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.

[0052] 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.

[0053] The publishing operation can be understood as a user uploading media content to a media content platform, editing the media content's publishing information, and then publishing it for other users to see. The special effect entry can be understood as a portal that allows users to quickly access the details page of a special effect object and use the special effect object. The presentation of the special effect entry can be set according to actual circumstances, for example, the special effect entry can be the special effect name of the special effect object.

[0054] After obtaining the third media content as described above, if the first application receives a publishing operation for the third media content, it can parse the third media content to determine the special effects 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 effects information in the target watermark. Then, after publishing the third media content, it can display the third media content and display a special effects entry corresponding to the special effects information on the third media content.

[0055] 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.

[0056] The embedding time can be understood as the specific time when the special effect identifier is added to the first media content. The embedding times of different special effect identifiers can be the same or different. The target special effect identifier can be the special effect identifier among multiple special effect identifiers whose special effect entry needs to be displayed. The attribute information of a special effect object can include the above-mentioned special effect identifier, special effect name, special effect icon, etc. This attribute information can serve as the special effect entry of the special effect object.

[0057] 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 based on the embedding time of each special effect identifier. 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. 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 in the top area, for example, so that the user can use the above-mentioned multiple special effect objects on the special effect details page.

[0058] Optionally, determining the 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.

[0059] 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.

[0060] 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.

[0061] The media content processing scheme provided by the embodiment of the present disclosure is as follows: a first application obtains first media content, wherein the first media content is an image or video; in response to a local storage operation or a media content generation operation on the first media content, processes the image of the first media content to embed special effect information, obtains second media content, and stores the second media content; obtains 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, parses the third media content to determine the special effect information, and displays a special effect entry corresponding to the special effect information on the third media content. By adopting the above technical scheme, the first application can embed the corresponding special effect information when storing or generating 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 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 interactivity of the media content and facilitating the recommendation and use of related special effects.

[0062] 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.

[0063] Among them, the transform domain watermark algorithm can be to convert the pixel information of the image into the transform domain, and then convert it into 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 the image into the discrete cosine transform domain to achieve watermark embedding and extraction, DWT can convert the image into the discrete wavelet transform domain to achieve watermark embedding and extraction, and DFT can convert the image into the Fourier transform domain to achieve watermark embedding and extraction.

[0064] 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 is modified into the encoded special effect information. The transform domain image with the added 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.

[0065] In the above scheme, special effects 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 common attack methods such as compression, noise, occlusion, etc., ensuring that the special effects information will not be lost due to editing, thereby improving the interactivity of the media content.

[0066] 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 watermarked image frame; and synthesizing the second media content based on the at least one watermarked image frame and other video frames in the video other than the target image frame. Optionally, the target image frames may be image frames extracted from the video at preset time intervals or all image frames of the video.

[0067] The target image frame may be an image frame into which special effect information is to be embedded. The target image frame may be part of or all of the image frames included in the video. The watermarked image frame may be an image frame already embedded with special effect information. The preset time interval may be the time interval for extracting image frames from the video as target image frames. The specific time interval may be set based on actual conditions. For example, the preset time interval may be 4 seconds, with one image frame extracted from the video every 4 seconds as the target image frame. Alternatively, the preset time interval may be set to the inverse of the video's frame rate. The frame rate may be the number of images refreshed per second in the video. In this way, all image frames in the video can be determined as target images.

[0068] When the first media content is a video, the media content processing device can first extract image frames from the video when embedding special effects information in the first media content, determine at least one extracted image frame as at least one target image frame, then embed special effects information in each target image frame to obtain a corresponding watermark image frame, thereby obtaining at least one watermark image frame; and synthesize the 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 effects information to at least one image frame of the video, the special effects information can be retained even if the image frames of the video are subsequently deleted, thereby improving the robustness of the special effects information.

[0069] In some embodiments, processing the image of the first media content to embed special effect information to obtain the second media content may include: for each special effect identifier, comparing the number of free bits of 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.

[0070] 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, it is determined whether the image of the first media content supports the addition of 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. 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 incorrect 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 special effect objects.

[0071] 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. For example, FIG3 is a schematic diagram of a watermark embedding provided by the embodiment of the present disclosure, in which the original image is the first media content mentioned above, 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 can be, for example, converting the special effect information into binary information, and modifying some 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 the target watermark added.

[0072] For example, Figure 4 is a schematic diagram of a watermark extraction process provided by an embodiment of the present disclosure. A watermark image is subjected to a DWT transform and a DCT transform to obtain a transform domain image. Hidden information, which is the special effect information encoded by the watermark, is read from the transform domain image. The hidden information is then watermark-decoded and validity-verified to obtain the special effect information. The validity-verification process here can be used to determine whether the decoded special effect information is correct, and can be implemented through self-verification.

[0073] In the disclosed embodiment, special effect information is embedded in media content through a 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 common attack methods such as compression, noise, and occlusion, ensuring that the special effect information will not be lost due to editing, thereby improving the interactivity of the media content.
