Abstract

Recent advances in digital technology have caused a huge increase in the use of 3D image data. In order to cope with large storage and transmission requirements, data compression is necessary. Although lossy techniques have shown to achieve higher compression ratios than lossless techniques, the latter are sometimes required, e.g., in medical environments. A lot of lossless image compressors do exist, but most of them don't exploit interframe correlations. In this paper we extend and refine a recently proposed technique which combines intraframe prediction and interframe modeling. However its current performance was still significantly worse than current state- of-the-art intraframe methods. After adding techniques often used in those state-of-the-art schemes and other refinements, a fair comparison with state-of-the-art intraframe coders is made. It shows that the refined method achieves considerable gains on video and medical images compared to these purely intraframe methods. The method also shows some good properties such as graceful compression ratio degradation when the interframe gap (medical volume data) or interframe delay (video) increases.
