Abstract

This paper aims at the design of an algorithm for image compression. For color images RGB components are extracted and converted to YCbCr as a preprocessing step and then block based Hybrid Transform is performed. After this preprocessing step image is quantized and projected lossless scanning is done to ensure the excellent quality of the recovered image. In this paper adaptive scanning approach is anticipated to compress the length of codeword to be transmitted and thus achieving higher compression ratios. Principle behind image compression is to reduce the number of bits required per pixel.
