2D A Compression Method of Digital Hologram Video using Domain Transforms and 2D Video Compression Technique

摘要

A domain conversion and a 2D video compression based on a compression method in which optimum compression conditions with the best compression efficiency are obtained by varying the conditions of the domain conversion method, domain conversion unit and compression parameters, and a compression method satisfying the obtained condition is selected. A digital hologram video compression method comprising the steps of: (a) generating a partial DH (Digital Hologram) image by dividing a digital hologram into segments according to a predetermined section; (b) performing domain conversion on the partial DH image according to each of a plurality of domain transformation methods to obtain domain transformation data; (c) generating the domain conversion data as a video sequence; (d) compressing a video sequence according to a two-dimensional video compressor, separately setting a parameter of the two-dimensional video compressor and compressing and generating a video sequence according to each set parameter; (e) reconstructing the compressed video sequence, restoring the reconstructed domain transformed data, inverse domain transforming the reconstructed domain transformed data, and reconstructing the reconstructed partial DH image; And (f) evaluating the reconstructed partial DH image and the initial partial DH image, and selecting an optimal domain conversion method and a parameter of the two-dimensional video compressor. The digital hologram video compression method extracts and compresses optimal conditions of the compression parameters such as the domain conversion method, the compression parameter, the CTU (Coding Tree Unit) size, the compression mode, and the GOP (group of prediction) Compared to the technology, the compression rate of the video is at least twice as high as the video quality.
