Hierarchical Segmentation-Based Image Coding Using Hybrid Quad-Binary Trees
Ashraf Ali Kassim, Wei Siong Lee, Dornoosh Zonoobi · IEEE Transactions on Image Processing · 2009
A novel segmentation-based image approximation and coding technique is proposed. A hybrid quad-binary (QB) tree structure is utilized to efficiently model and code geometrical information within images. Compared to other tree-based representation such as wedgelets, the proposed QB-tree based method is more efficient for a wide range of contour features such as junctions, corners and ridges, especially at low bit rates.
