| Abstract: |
A two-stage lossless compression method based on a binary tree representation of colors and on context-based arithmetic coding has been recently proposed. We propose two improvements to this method: merge-based color quantization instead of the original spitting strategy, and context tree modeling optimized for each layer separately. The proposed method achieves better compression performance, and a better reproduction quality in the color progression. |
