Abstract

An adaptive image-coding algorithm for compression of medical images in the wavelet domain is determined using a modified curvelet transform with a SPIHT encoder. The objective results tested for different medical images show that the proposed scheme attains high PSNR and high compression ratio as compared with existing image compression methods.
