Wavelet Based Image Compression

Images require substantial storage and transmission resources, thus image compression is advantageous to reduce these requirements. Image compression is a key technology in transmission and storage of digital images because of vast data associated with them. This research suggests a new image compression scheme with pruning proposal based on discrete wavelet transformation (DWT). The effectiveness of the algorithm has been justified over some real images, and the performance of the algorithm has been compared with other common compression standards. The algorithm has been implemented using Matlab. Experimental results demonstrate that the proposed technique provides sufficient high compression ratios compared to other compression techniques.
