STUDY ON IMAGE COMPRESSION BASED ON CURVELET TRANSFORM

Abstract

In this work, the conventional compression standards like JPEG and JPEG2000 are studied extensively, and the procedure is extended and made compatible with curvelets. Experimental results show that the proposed method produces somewhat similar SSIM and PSNR values that of conventional standards, but improvement has noticed in the decrement of edge mismatch error but with poor performance in compression ratio. To mitigate this problem compressive sensing is used, which samples the signal in less number of samples and better sample reduction has been observed.
