Context-Based Trit-Plane Coding for Progressive Image Compression

Seungmin Jeon, Kwang Pyo Choi, Youngo Park, Chang-Su Kim

CVPR 2023poster

Trit-plane coding enables deep progressive image compression, but it cannot use autoregressive context models. In this paper, we propose the context-based trit-plane coding (CTC) algorithm to achieve progressive compression more compactly. First, we develop the context-based rate reduction module to…

DPICT: Deep Progressive Image Compression Using Trit-Planes

Jae-Han Lee, Seungmin Jeon, Kwang Pyo Choi, Youngo Park, Chang-Su Kim

CVPR 2022oral

We propose the deep progressive image compression using trit-planes (DPICT) algorithm, which is the first learning-based codec supporting fine granular scalability (FGS). First, we transform an image into a latent tensor using an analysis network. Then, we represent the latent tensor in ternary digi…
