Image Compression and De-compression

In document management and transmission systems, the compression and decompression of continuous-tone images is very important. This paper explains an image representation scheme to the standard Discrete Cosine Transformation (DCT). Based on Gaussian derivatives, we are developing this scheme inside a Joint Photographic Experts Group (JPEG) framework. By using this scheme, we can compress and decompress the continuous-tone images. This project is user-friendly and works very efficiently.
