IMPROVED FRACTAL BASED IMAGE COMPRESSION FOR GRAYSCALE USING COMBINED SHEAR AND SKEW TRANSFORMATIONS

Sarabjeet Kaur, Er. Anand Kumar Mittal

Abstract :

Now a days, image compression techniques work with great efficiency to achieve higher compression. The fractal image compression is a lossy type of image compression technique. This technique provides very high compression ratios which are highly in demand in CCTV cameras and grayscale implementation. The image is oken into domain of the smaller range blocks and these range blocks are transformed according to specified criteria. The similar blocks located are then reunited to form the compressed image approximation. In the fractal approach, maximum redundant blocks are tried to be achieved which provides better compression ratios .In this paper, a combined shear and skew based transformation approach is implemented to attain better results.
