Abstract
The present disclosure relates to an image processing method, readable medium and electronic device. The method comprises: acquiring a watermark image, wherein the watermark image is an image embedded with a foreground watermark, and the foreground watermark is generated by watermark information; determining a first image channel embedded with the foreground watermark and a second image channel not embedded with the foreground watermark in the watermark image, and determining a channel difference feature map of the watermark image according to channel information of the first image channel and channel information of the second image channel; performing feature enhancement processing on the channel difference feature map to obtain a first watermark enhanced feature map of the watermark image, wherein the first watermark enhanced feature map is used for extracting the watermark information of the watermark image.
