Image Encoding Method, Apparatus, Storage Medium And Electronic Device

A non-transitory computer-readable storage medium, storing computer program instructions, which, when executed by a processor, cause the processor to implement the following steps:

• encoding an image to be encoded based on a pixel height of a watermark image and a vertical search range of an image encoder to obtain a plurality of slice data streams in a first set mode of the image to be encoded;
• acquiring a target image block from the image to be encoded based on information of a target region in which the watermark image is inserted into the image to be encoded, wherein the target image block is an image block adjacent to the target region;
• generating, based on the target image block and the watermark image, a watermark image to be encoded having a pixel height no more than a sum of the pixel heights of two slices;
• encoding the watermark image to be encoded to obtain a watermark slice data stream;
• and
• generating, based on the watermark slice data stream and the plurality of slice data streams in the first set mode, a plurality of slice data streams in a second set mode of the image to be encoded.

An electronic device, comprising:

• a processor;
• a memory for storing executable instructions of the processor;
• wherein the processor is configured to read the executable instructions from the memory and execute the instructions to implement the following steps:
• encoding an image to be encoded based on a pixel height of a watermark image and a vertical search range of an image encoder to obtain a plurality of slice data streams in a first set mode of the image to be encoded;
• acquiring a target image block from the image to be encoded based on information of a target region in which the watermark image is inserted into the image to be encoded, wherein the target image block is an image block adjacent to the target region;
• generating, based on the target image block and the watermark image, a watermark image to be encoded having a pixel height no more than a sum of the pixel heights of two slices;
• encoding the watermark image to be encoded to obtain a watermark slice data stream;
• and
• generating, based on the watermark slice data stream and the plurality of slice data streams in the first set mode, a plurality of slice data streams in a second set mode of the image to be encoded.
