| Image compression is the process of compacting data and maintaining the necessary information to represent an image. Image compression minimizes the memory requirements for storing data, especially when dealing with images that have large dimensions. This research focuses on image compression using wavelet transform to obtain "visually lossless" compression. A new technique which achieves a better compression ratio than the existing methods is presented. Different standards such as: BMP, JPEG2000 and JPEG are compared with the new algorithm. |
