A Modified Image Template for FELICS Algorithm for Lossless Image Compression

Abstract

In this paper, a lossless image compression technique using FELICS algorithm is used for compressing the image. In this technique the pixels of image are coded using adjusted binary coding and Golomb-Rice coding. The coding of the pixel depends upon the position of the pixel in the image. The original image template in the FELICS algorithm has four different cases for position of pixel, but in this modified image template for FELICS algorithm we have proposed five cases. The quality of compressed images is compared by using various image quality parameters. After using this modified image template, we get slightly better compression ratio and reduced bit rate, this is achieved without affecting the other image quality parameters.
