Segmentation-based progressive image coding

The authors present, as an image pyramid, an adaptive, tree-structured segmentation to facilitate progressive transmission. The new image pyramid is semantically more powerful than regular tessellations while syntactically simpler than free segmentation. This good compromise between adaptability and complexity is a key to the high compression ratios achieved by the proposed image coder. The performance is further enhanced by exploiting the statistical dependency between layers of the image pyramid.<>
