Undecimated image processing method and device

An electronic device, comprising a processor, a memory, and a program or an instruction stored on the memory and executable on the processor, wherein the program or instruction is executed by the processor to perform an undecimated image processing method, comprising:

• acquiring an image to be processed;
• inputting the image to be processed into an image processing network, to obtain an output image, wherein a resolution of the output image is the same with a resolution of the image to be processed,
• wherein the image processing network comprises:
• an analysis module, a synthesis module and at least one processing module, the inputting the image to be processed into the image processing network to obtain the output image comprises:
• inputting the image to be processed into the analysis module to perform feature analysis, and outputting a feature tensor image;
• inputting the feature tensor image into the processing module for processing, and outputting a processed feature tensor image, wherein a resolution of the feature tensor image outputted by the processing module is the same with the resolution of the image to be processed;
• and
• synthesizing, by the synthesis module, at least one feature tensor image outputted by the at least one processing module to obtain the output image.
