CVPR 2023 - Context-Based Trit-Plane Coding for Progressive Image Compression

In this episode we discuss Context-Based Trit-Plane Coding for Progressive Image Compression by Seungmin Jeon, Kwang Pyo Choi, Youngo Park, Chang-Su Kim. The paper proposes the context-based trit-plane coding (CTC) algorithm for progressive image compression. CTC enables compact encoding of trit-planes by developing a context-based rate reduction module to estimate trit probabilities accurately. The context-based distortion reduction module refines partial latent tensors from the trit-planes to improve image quality. The proposed CTC algorithm outperforms the baseline trit-plane codec significantly and increases time complexity marginally.
