小波分析压缩感知在图像复原中的应用研究
Application of wavelet analysis and compressed sensing in image restoration
摘要
Abstract
The compressed sensing theory is a novel data acquisition, coding and decoding theory under the condition that signal is sparse or compressible. The two-dimension wavelet decomposition, reconstruction algorithm and compressed sensing theory are introduced. It is pointed out that the theory of compressed sensing based on wavelet transform has the advantages of low computational complexity, simple structure and easy to realize in the processof image restoration. The experiment result means that the algorithm compared with other typical restoration algorithm, when the processing outputs are similar, takes up less observation data,storage space and calculation quantity. It can effectively improve both subjective and objective qualifies of the compressed images with low bit rate, and achieve better performance than other traditional algorithms.关键词
