Abstract

Based on the sparse characteristic of image signal in Contourlet transform domain, the theory of image Contourlet transform is analyzed, and the image Compressive Sensing(CS) reconstruction method is proposed based on the Contourlet transform. Because the basis of Contourlet transform is not orthogonal strictly and can not construct orthogonal matrix, this paper proposes an image reconstruction method which is based on ameliorative gradient projection algorithm to improve the conventional reconstruct algorithm. The image reconstruction method which is based on ameliorative gradient projection algorithm can realize the high quality image reconstructed with low sampling rate. Experimental result shows that the proposed method has good robustness.
