In this paper, we develop an image compression algorithm based on an information-theoretic analysis of transform coding in the end-to-end imaging process. Our analysis accounts for the radiance-field statistics,
One of the best image compression techniques is using wavelet transform. It is comparatively new and has many advantages over others. Wavelet transform uses a large variety of wavelets for decomposition of images. The state of the art coding techniques like EZW, SPIHT (set partitioning in ...

Transform based image compression has difficulty with image regions containing edges. Edge compensated transform coding (ECTC) addresses this problem by preprocessing to remove edges. This preprocessing is adapted to transform coding. The edge information is sent in a side channel and the edges are re...

Block Transform In subject area: Computer Science A block transform is a technique used in image and speech coding that involves dividing an image or speech signal into sub-images and independently coding each sub-image. However, at low bit rates, this technique can result in a "blocking" ...
