Wavelet based fast fractal image compression

Image compression is a significant technology in the transmission and storage of digital images. The importance of image compression is that to preserve the visual feature of the image. One of the finest image compression techniques is using wavelet transform which have comparatively had several benefits over other. Basically wavelets are confined in both time and frequency. Wavelet transformations perform multilevel decomposition of image that is diving image into sub parts of image at different measures. Discrete wavelet transform examined the signal at a different frequency bandwidth that is approximate band and detail band. Using wavelet with balance resolution at any time and frequency gives a better signal illustration using multilevel analysis. Therefore, at very low bit rate the suggested method improves the visual feature of decoded image.
