Abstract

The invention discloses a coding and decoding network training method and device, equipment and a storage medium. The method comprises the following steps: when each round of training is executed, acquiring a sample image; inputting the sample image into a coding and decoding network, and sequentially performing compression coding processing and decoding recovery processing on the sample image by using the coding and decoding network to obtain a decoded image corresponding to the sample image; determining an image loss value and a decoding loss value corresponding to the coding and decoding network according to the sample image and the decoding image corresponding to the sample image; determining a network loss value corresponding to the coding and decoding network according to the image loss value and the decoding loss value corresponding to the coding and decoding network; and after multiple rounds of training, when the network loss value corresponding to the coding and decoding network is within a preset network convergence range, determining that the coding and decoding network is converged. According to the invention, the distortion condition of a decoded image is controlled while the definition of the decoded image is ensured, the quality of the recovered image is relatively high, and the decoded image does not need to be repaired by using a repair network.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a training method, device, equipment and storage medium for a codec network. Background technique [0002] With the popularization of smart devices, more and more images are produced. High-resolution images often have a large amount of data. No matter in the storage scene or in the transmission scene, images with a large amount of data will take up more Resources (storage space, transmission resources). In order to solve this problem, image compression technology came into being. Using image compression technology to encode the original image, the original image can be compressed into compressed data with a small amount of data, and then the compressed data can be decoded, and the compressed data can also be restored to the original image. [0003] Currently, commonly used image compression technologies are WebP image compression technology and BPG (Better...
