[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0048] The terms "including" and "having" and any variations thereof mentioned in the embodiments of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0049] At present, among the existing methods of adding watermarks, some add too few watermarks and the positions are too fixed, which can be easily circumvented by screenshots or other methods; others add too many tiled watermarks, resulting in poor image display. That is, if the image is tiled, too many watermarks will be added, which will interfere with viewing the image and affect the experience.

[0050] Based on this, the embodiments of the present application provide a picture-based watermark processing method, device and electronic device, which can solve the technical problem that the watermark added to the picture by the existing watermarking method can be easily circumvented by screenshots or other methods.

[0051] The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

[0052] Figure 1 The following is a flow chart of a watermark processing method based on an image provided in an embodiment of the present application. Figure 1 As shown, the method includes:

[0053] Step S110, obtaining a target image to be watermarked.

[0054] As a possible implementation, a target picture to be watermarked is read, for example, a landscape picture, a person picture, an object picture, etc.

[0055] Step S120 , based on the target image, all main objects and the object positions of the main objects in the target image are identified by using an image segmentation method, and a corresponding relationship between the object positions and the object information of the main objects is determined.

[0056] The main object may include at least one of an object object, a person object, an animal object, and a plant object.

[0057] As an optional implementation, after acquiring the image, segmentation technology is used to identify the positions of all objects in the image, read the coordinates and record them, and correspond to the object information.

[0058] For example:

[0059]

[0060] The four coordinates in "body":"[[263,505],[273,2775],[190,2928],[2871,2958]]" represent the four coordinate points of the body in the image, from left to right and from top to bottom. The four coordinates here are just examples. In real scenes, if the body, clothes, etc. are irregular, there may be many coordinates.

[0061] In the embodiment of the present application, the target image corresponds to a preset parameter interference value, and the parameter interference value is used to characterize the relative position relationship between the watermark to be added and the object center position in the object position. As an example, the relative position relationship includes the target distance and / or relative tilt between the watermark to be added and the object center position in the object position; the larger the parameter interference value, the smaller the target distance and / or relative tilt between the watermark to be added and the object center position, or the larger the parameter interference value, the larger the target distance and / or relative tilt between the watermark to be added and the object center position.

[0062] Exemplarily, the parameter interference value includes a first parameter interference value, a second parameter interference value, a third parameter interference value, a fourth parameter interference value, and a fifth parameter interference value in order of watermark interference degree from small to large:

[0063] The first watermark placement position corresponding to the first parameter interference value is located at the corner position of the target image, and the corresponding watermark coverage is less than the preset coverage;

[0064] The distance between the second watermark placement position corresponding to the second parameter interference value and the range boundary of the position range of the main object in the target image is maintained at a first preset distance, and the second watermark placement position is obtained by calculating a first average value of each coordinate point corresponding to the object position and offsetting the first preset offset distance based on the first average value;

[0065] The third watermark placement position corresponding to the third parameter interference value is located at the range boundary of the position range of the main object in the target image, and the third watermark placement position is obtained by calculating the second average value of each coordinate point corresponding to the object position and offsetting the second preset offset distance based on the second average value; wherein the second preset offset distance is less than the first preset offset distance;

[0066] The fourth watermark placement position corresponding to the fourth parameter interference value is located within the position range of the main object in the target image, and the distance from the center position of the object is maintained at a second preset distance. The fourth watermark placement position is obtained by calculating a third average value of each coordinate point corresponding to the object position and offsetting a third preset offset distance based on the third average value; wherein the third preset offset distance is less than the second preset offset distance;

[0067] The fifth watermark placement position corresponding to the fifth parameter interference value is located at the center of the object, and the fifth watermark placement position is obtained by calculating the center of the object.

[0068] Exemplarily, a parameter interference value interference_degree is set, and several values ​​can be set as needed: 0 (first parameter interference value), 0.25 (second parameter interference value), 0.5 (third parameter interference value), 0.75 (fourth parameter interference value), and 1 (fifth parameter interference value).

[0069] Among them, 0 is the weakest, and is generally best at the rightmost vertex position with the least interference. The watermark is placed at the corner of the image with relatively small coverage; 0.25: The watermark is close to the body area but not in the center. The average value of each coordinate point is calculated and slightly offset, such as moving a certain distance in a certain direction of the average value; 0.5: The watermark is at the edge of the body area, and the watermark is placed slightly offset from the average value, such as above or below the body; 0.75: The watermark is near the center of the body, but does not completely cover the center. After calculating the average value, it is slightly offset by a small distance so that the watermark is near the center but not completely covered; 1: The watermark is completely in the center of the body, and the watermark is placed directly at the calculated center position.

[0070] By using the first parameter interference value, the second parameter interference value, the third parameter interference value, the fourth parameter interference value and the fifth parameter interference value, the watermarking position calculated according to the parameter interference value of the watermark is made more accurate.

[0071] Step S130 : determining the position to be watermarked corresponding to each main object in the target image according to the parameter interference value through the corresponding relationship.

[0072] In a possible implementation, calculations are performed according to detailed needs, and a set of watermark positions to be added is calculated according to an algorithm, that is, the coordinate position of each object in the picture corresponding to the watermark to be added.

[0073] For example, Figure 2 As shown, this step S130 may specifically include the following steps: step S210, determining the first initial watermark position corresponding to each object position according to the parameter interference value, and determining the second initial watermark position corresponding to each main object in the target image through the corresponding relationship based on the first initial watermark position; step S220, determining the watermark intersection position between multiple second initial watermark positions corresponding to multiple different main objects according to the second initial watermark position, and judging whether there is watermark mutual interference between multiple second initial watermark positions according to the watermark intersection position; step S230, if there is watermark mutual interference, adjusting the target second initial watermark position with watermark mutual interference to obtain the adjusted final watermark position. In this way, it is possible to avoid the situation where watermarks interfere with each other among multiple watermarks added to the image.

[0074] Optionally, the above-mentioned adjustment of the target second initial watermark position to be watermarked where watermarks interfere with each other to obtain the adjusted final watermark position may specifically include the following steps: reducing the position range size of the target second initial watermark position to be watermarked where watermarks interfere with each other to reduce the interference intensity of the watermarks interfering with each other to obtain the reduced final watermark position; and / or replacing the position vertex of the target second initial watermark position to be watermarked where watermarks interfere with each other to obtain the replaced final watermark position, wherein the position vertex is a distance endpoint formed by a target distance in a relative position relationship corresponding to a relative direction of the target second initial watermark position relative to the center position of the object and a parameter interference value, and replacing the position vertex includes replacing the distance endpoint corresponding to the first relative direction with the second relative direction.

[0075] As an example, calculate the intersection of watermarks of different objects. If they interfere with each other, replace other vertices. For example, 0 is the weakest, and the rightmost vertex is generally the best. However, if the rightmost vertex is very close to other objects and there is interference, replace it with the leftmost vertex. As another example, reduce the range of the watermark position to minimize the interference.

[0076] In the embodiment of the present application, the position vertex (such as the left vertex) of the target second initial position to be watermarked where watermarks interfere with each other is replaced to obtain the final position to be watermarked after the replacement (such as the right vertex), wherein the position vertex is the distance endpoint formed by the relative direction (including the left, right, top, bottom and other relative directions) of the target second initial position to be watermarked relative to the center position of the object and the target distance corresponding to the parameter interference value, and the replacement of the position vertex (including the left vertex) includes the replacement result of the distance endpoint (i.e. the right vertex) corresponding to the replacement of the first relative direction (such as the left) with the second relative direction (such as the right). Through the above-mentioned processing methods, the degree of mutual interference between multiple watermarks can be eliminated or reduced more efficiently and effectively.

[0077] As an optional implementation, each subject object corresponds to a plurality of position coordinates, and the plurality of position coordinates are used to characterize the coordinates of the range boundary points of the position range of the subject object in the target image. For example, the position range of the second initial position to be watermarked of the target mentioned above. In this way, the data of the position of each subject object in the target image is made more accurate.

[0078] Through the above watermark position calculation process, a coordinate set is finally obtained, for example:

[0079]

[0080] Step S140, according to the selection instruction for the main object, determine the target position to be watermarked from the positions to be watermarked corresponding to the main object, and perform watermarking processing on the target position to be watermarked in the target image based on the watermark to be added to obtain the target image result after watermarking.

[0081] For example, watermarks are added as needed. For example, if watermarks need to be added to all items, watermarks are added to all items; if watermarks are added only to human body parts, watermarks are added only to human body parts; if watermarks are added to animals, watermarks are added to animals.

[0082] As an optional implementation, in step S140, according to the selection instruction for the subject object, the target position to be watermarked is determined from the positions to be watermarked corresponding to the subject object, which may specifically include the following steps: in response to the selection operation for all subject objects, the target subject object selected corresponding to the selection operation is determined from all subject objects; and the target position to be watermarked corresponding to the target subject object is determined from all the positions to be watermarked corresponding to all subject objects. Through the above processing method, it is possible to selectively add watermarks to the subject object, making the effect of adding watermarks to the picture more flexible.

[0083] In an optional implementation, the target image corresponds to a target object to be watermarked; if the target object to be watermarked is all the object objects in the target image, the selection operation is a selection operation for all the object objects in all the subject objects, and the watermark to be added is added to all the object objects in the target image result; if the target object to be watermarked is all the subject objects in the target image, the selection operation is a selection operation for all the subject objects, and the watermark to be added is added to all the subject objects in the target image result; if the target object to be watermarked is all the person objects in the target image, the selection operation is a selection operation for all the person objects in all the subject objects, and the watermark to be added is added to all the person objects in the target image result; if the target object to be watermarked is the body parts of all the person objects in the target image, the selection operation is a selection operation for all the person objects in all the subject objects, and the body parts of all the person objects in the target image result are added to the watermark to be added.

[0084] For example, if you need to add watermarks to all places in the picture, then add watermarks to all objects such as items and people in the picture; if you only need to add watermarks to people, then add watermarks to the coordinates of the people; if you only need to add watermarks to animals, then only add watermarks to animals. Through the above processing methods, it is possible to achieve flexible control and precise control of the watermarking position.

[0085] In the embodiment of the present application, according to the content of different main objects in the picture, the added watermarks are all on the main objects in the picture, so as to add watermarks to important people or objects in the picture. The added watermark position can be directly added to the objects and people in the picture, and the watermark can be added selectively, either all of them or selectively added to certain objects, so that the watermark placement is more accurate and not easy to be circumvented, thereby avoiding the watermark being too fixed in position and resulting in poor effect and easy to be circumvented by screenshots, etc. Moreover, by adding watermarks only to the main objects in the picture, the number of watermarks is also greatly reduced, thereby improving the overall picture effect of the watermarked picture, so that after the picture is watermarked, the watermark does not appear abrupt, thereby realizing a method of intelligently adding watermarks to people or objects in the picture.
