LOSSY COLOR IMAGE COMPRESSION USING NON LINEARIZATION AND COLOR REDUCTION

Apoorva Hegde, Sumitha Deepak

Abstract: Color Image compression is a technique used to reduce the bandwidth required and space needed to store the data when streaming the image across the network. In the modified version of the image compression and reconstruction we use a block optimization technique such as rank filtering to optimize the image. It is then followed by color reduction which is achieved by byte compression technique to achieve optimum compression. A desired amount of compression is achieved using the proposed compression technique. PSNR calculated is then compared with the previous technique. The simulation tool used is MATLAB to implement this algorithm.

Keywords: Image Compression, Rank Filtering,Color Reduction And Byte Compression.
