摘要：Digital Images play a very important role for describing the detailed information about man, money, machine almost in every field. The various processes of digitizing the images to obtain it in the best quality for the more clear and accurate information leads to the requirement of more storage space and better storage and accessing mechanism in the form of hardware or software. In this paper we apply a technique for image compression. Our proposed approach is the combination of several approaches to make the compression better than the previous used approach. In this technique we first apply walsh transformation. Split all DC values form each transformed block 8x8.After that we apply arithmetic coding for compress an image. In this paper we also present a brief survey on several Image Compression Techniques
