Abstract
This application discloses an image processing method, device, system, electronic equipment, and storage medium, applied at the encoding end. The method includes extracting a one-dimensional feature vector from an original image block; transforming the original image block into a multidimensional feature map based on the one-dimensional feature vector; quantizing and encoding the one-dimensional feature vector to generate a first code stream; discretely encoding the multidimensional feature map to generate a second code stream, thereby efficiently compressing the spatial-independent vector and the multidimensional feature map; and sending the first and second code streams to the decoding end. Since the encoding stream comprises two layers each representing different types of image information, image reconstruction from the two-layer code streams maintains information integrity even at low bit rates, thus improving visual effects and experience.
