Abstract

This paper developed a progressive hierarchical algorithm combining image texture complexity and wavelet coefficient characteristics to meet the requirements of remote desktop environment. Firstly, the algorithm allocated bits for each image block according to texture complexity in order to improve the utilization of target bit budget. Then, it optimized the hierarchical structure of high-frequency detail components in the progressive hierarchical algorithm by analyzing the order of the importance of different subbands features in the image block. And it also designed a progressive hierarchical algorithm that added subbands transmission layer by layer based on the wavelet coefficient characteristics. Finally, according to the allocated bits and the selected layering method, the paper implemented a codec system for progressive transmission of each image block. Simulation experiments show that the proposed progressive transmission algorithm can reconstruct better images in different image transmission environments, and is more in line with the visual perception characteristics of the human eye. The algorithm is more adaptive to weak networks and performs better in the field of desktop remote video image transmission and processing.
