Abstract

Multi-resolution is the good characteristics of wavelet transform. In wavelet transform domain, high frequency subband of image is sparse. Less high frequency coefficient can be sampled by compressed sensing technology. In this study, for an image, a sparse representation in the wavelet transform domain is found. Image is reconstructed by the orthogonal matching pursuit (OMP) , compressive sampling matching pursuit (CoSaMP), iteratively reweighted least square (IRLS) and Suspace Pursuit (SP), respectively. Different wavelet basis and sampling rate which affect the quality of the reconstruction are discussed. Experimental result shows that performance of IRLS is the best, OMP are easy implementation and fast speed, and Coif3 has a better performance than the other wavelet basis.
