Abstract

Image restoration is a process of reconstructing the image that not only enhancing information, texture and brightness but also removing the noise for restoring the original image. To obtain the best restored image multi-resolution based compressive sensing (CS) methodology was implemented, this enhancing approach has the characteristics of enhances an image at different compressive ratios using iterative procedure and results compared between iterations and performance parameter. PSNR (Peak Signal Noise Ratio) is the observing performance parameter for different ratio levels of the image, RMSE, SSIM are the other factors. Our approach results in strong sparse representation to pursue from patch-based sparse compressive sensing (PSCS). PSCS is an adaptive approach to multiresolution analysis, patch sparsest matching for compressive sensing to remove noise and enhances the image restoration possibility. Experimental results showcase for different images with different resolutions. At compressive ratios of 20, 40, 60 and 80 PSCS performance enhanced by 15%, 14%, 8% and 6% when compared with TV- normalization of compressive sensing.
