Image enhancement processing method and apparatus, device and storage medium

An electronic device, comprising:

• at least one processor;
• and
• a memory communicatively connected with the at least one processor;
• wherein the memory stores an instruction executable by the at least one processor, and the instruction is executed by the at least one processor to enable the at least one processor to:
• obtain, in response to an input image read, a color space corresponding to the input image and all color pixels of at least one color component in the color space;
• determine sharpened pixel values respectively corresponding to pixel positions of all the color pixels;
• determine smoothed sharpened pixel values respectively corresponding to all the pixel positions based on the sharpened pixel values respectively corresponding to the pixel positions of all the color pixels;
• obtain a to-be-coded image corresponding to the input image according to the smoothed sharpened pixel values respectively corresponding to all the pixel positions.

A non-transitory computer readable storage medium with a computer instruction stored thereon, wherein the computer instruction is configured to enable a computer to:

• obtain, in response to an input image read, a color space corresponding to the input image and all color pixels of at least one color component in the color space;
• determine sharpened pixel values respectively corresponding to pixel positions of all the color pixels;
• determine smoothed sharpened pixel values respectively corresponding to all the pixel positions based on the sharpened pixel values respectively corresponding to the pixel positions of all the color pixels;
• obtain a to-be-coded image corresponding to the input image according to the smoothed sharpened pixel values respectively corresponding to all the pixel positions.
