MULTI-LAYERED IMAGE COMPRESSION USING STRUCTURE TENSOR FOR TEXTURE IDENTIFICATION

Compression of images using transform methods has been of interest for many years. In this paper we propose a new multilayer image compression method which uses wavelet and contourlet transforms. We used structure tensor for identifying texture regions of the image by producing a binary mask. Then we apply wavelet to smooth regions and use contourlet transform for texture area. The proposed method avoids the redundancy of contourlet which has …
