Video encoding and decoding device and method based on deep auto-encoder

Abstract

The present disclosure provides a video coding and decoding device and method based on depth automatic coder. The device comprises: a depth automatic coder module, a neural network codec module, and a mixed codec module. The depth automatic coder module comprises a depth automatic coder. The depth automatic coder comprises a coding end. The coding end is used for performing first compression on an original video to obtain first-compressed data. The neural network codec module is used for performing coding and compression on a decoding end parameter, so as to generate a decoding end parameter that has been coded. The mixed codec module is used for performing mixed coding on the first-compressed data and the decoding end parameter that has been coded, so as to obtain the video compression data. In the present disclosure, the compression rate of video data is improved by constructing a coding end and a decoding end that are symmetrical in the structure and by performing secondary compression and decompression on the video data. Because of a non-linear characteristic of an artificial neural network, the integration of video data compression and encryption is implemented, by using a parameter of the artificial neural network as a key. The coding result of the video data contains a characteristic of the video data, which facilitates the classification and search of the video data and provides a broad development space and application prospect. Without the complicated coding and decoding process in manual design, the automatic extraction of a data characteristic by the depth automatic coder greatly reduces manual intervention, so that the automation of the coding process is implemented, the implementation is simple, and the scalability is good, and accordingly, the present invention can be used to compress video data and can also compresses other data.

Description

technical field [0001] The present disclosure relates to the field of video compression and decompression, and in particular to a video encoding and decoding device and method based on a deep autoencoder. Background technique [0002] With the advent of the Internet era, the massive generation of video data puts forward higher requirements on the transmission capacity. In order to alleviate the pressure of transmission, video coding and decoding technology came into being, and played a huge role in compressing video for transmission. [0003] The traditional video coding technology uses different methods to eliminate the various types of redundancy existing in the video so as to achieve the purpose of compressing the video. For example, for temporal redundancy, spatial redundancy, visual redundancy and coding redundancy of video, technicians respectively adopt methods such as inter-frame coding, intra-frame coding, quantization and entropy coding. Transformation is also a ...
