Image processing method and apparatus, computer readable storage medium, and computer device

An apparatus, comprising processing circuitry configured to:

• acquire a to-be-processed image;
• zoom out the to-be-processed image from a first size to a second size;
• perform a splicing processing on a first output feature map from a first processing unit and the to-be-processed image of the second size to obtain a first spliced output feature map for input into a second processing unit of a first codec;
• determine a first feature map based on at least a feature reconstruction on the to-be-processed image of the second size by a first codec of a first set of coding units, the first set of coding units comprising at least a pair of encoder and decoder, a coding unit in the first codec including at least the first processing unit and the second processing unit;
• zoom in the first feature map to the first size;
• perform a splicing processing on the to-be-processed image of the first size and the first feature map of the first size to obtain a spliced feature map;
• and
• perform a feature reconstruction on the spliced feature map by a target codec, to obtain a target image, the target codec comprising a target set of coding units, a first subset of the target set of coding units corresponding to the first set of coding units.

A non-transitory computer-readable medium storing instructions which when executed by a computer cause the computer to perform:

• acquiring a to-be-processed image;
• zooming out the to-be-processed image from a first size to a second size;
• performing a splicing processing on a first output feature map from a first processing unit and the to-be-processed image of the second size to obtain a first spliced output feature map for inputting into a second processing unit of a first codec;
• determining a first feature map based on at least a feature reconstruction on the to-be-processed image of the second size by a first codec of a first set of coding units, the first set of coding units comprising at least a pair of encoder and decoder, a coding unit in the first codec including at least the first processing unit and the second processing unit;
• zooming in the first feature map to the first size;
• performing a splicing processing on the to-be-processed image of the first size and the first feature map of the first size to obtain a spliced feature map;
• and
• performing a feature reconstruction on the spliced feature map by a target codec, to obtain a target image, the target codec comprising a target set of coding units, a first subset of the target set of coding units corresponding to the first set of coding units.
