Abstract:
Due to the increasing requirements for transmission of images in computer, mobile systems, the research in the field of image compression has increased significantly. Image compression plays a important role in digital image processing , it is also very important for efficient transmission and storage of images. Image compression means reducing the size of graphics file, without compromising on its quality. Depending on the reconstructed image, two techniques for compression exist : lossy techniques and lossless techniques. This paper is a survey for lossless image compression using Discrete Cosine Transform (DCT).
