Abstract

The invention provides a multi-description encoding and decoding method and system based on a convolutional auto-encoder. The encoding method comprises: receiving image information, carrying out convolution processing on the image information by using a convolution auto-encoder to obtain convolution characteristics, compressing the input image information into a potential space representation by the convolution auto-encoder, and then reconstructing output through the characteristics of the convolution auto-encoder, so that the output is infinitely close to the input; Dividing the obtained convolutional features into two descriptions, each description comprising two subsets, respectively encoding the two descriptions to obtain two multi-description code streams, and respectively transmitting the two multi-description code streams through different channels. On the premise that the packet loss problem is solved, the coding efficiency can be improved, and a reconstructed image with higheraccuracy can be obtained.

Description

technical field [0001] The present disclosure relates to the field of communication technology and the field of computer technology, in particular to a multi-description encoding and decoding method and system based on a convolutional autoencoder. Background technique [0002] Image is a similar and vivid description of objective things, and a relatively intuitive way of expressing objective objects. It contains information about the described object and is the main source of information for people. According to statistics, about 75% of the information a person gets comes from vision. Entering the information age, people will rely more and more on computers to obtain and utilize information, and the digitized multimedia information has a large amount of data, and there is a big gap between the computer storage resources and network bandwidth that current hardware technology can provide. In this way, it has caused great difficulties in the storage and transmission of inform...
