| Research Abstract |
In this study, we have developed a lossless re-encoding technique which can compress the existing image contents without any additional loss of quality. The basic algorithm was mainly designed for JPEG and MPEG-1 schemes : the international coding standards widely used for images and videos. As a result, 10.30% bit-rate savings are achieved against the already compressed image data. This new technology enables us to archive a large amount of the existing image contents with efficiency comparable to state-of-the-art coding schemes.
