Image Compressed Sensing Based on Universal HMT of the Dual-tree Wavelets
|
Abstract:
The standard Compressed Sensing(CS) reconstructions of image exploit simply the sparse priors of the wavelet coefficients,ignoring the structural information of the wavelet coefficients.In this paper,the Hidden Markov Tree(HMT ) model is integrated in the compressed sensing,which has been found successful in capturing the key features of the joint probability density of the wavelet coefficients of real-world image.An optimization issue which is similar to the standard compressed sensing is derived from the ...
