Check out our work ANFIC: Image Compression Using Augmented Normalizing Flows.

1. ANFIC is an end-to-end learned image compression system based on Augmented Normalizing Flows (ANF). ANF is a new type of flow model, which stacks multiple variational autoencoders (VAE) for greater model expressiveness.

2. ANFIC advances further compression efficiency by stacking and extending hierarchically multiple VAE’s. The invertibility of ANF, together with our training strategies, enables ANFIC to support a wide range of quality levels without changing the encoding and decoding networks.

3. Extensive experimental results show that in terms of PSNR-RGB, ANFIC performs comparably to or better than the state-of-the-art learned image compression.

ANFIC is open source! The paper and the code are available at:

Check out our recent work CANF-VC: conditional augmented normalizing flows for video compression.

1. CANF-VC represents a new attempt that leverages the conditional ANF to learn a video generative model for conditional inter-frame coding.

2. CANF-VC extends the idea of conditional coding to motion coding, forming a purely conditional coding framework.

3. Extensive experimental results on commonly used datasets confirm the superiority of CANF-VC to the state-of-the-art methods.

CANF-VC is open source! The paper and the code are available at:

The JPEG Committee has launched the learning-based image coding activity, also referred to as JPEG AI. This activity aims to find evidence for image coding technologies that offer substantially better compression efficiency than available image codecs with models obtained from a large amount of visu...
