Two-pass Light Field Image Compression for Spatial Quality and Angular Consistency
Bichuan Guo, Jiangtao Wen, Yuxing Han
The quality assessment of light field images presents new challenges to conventional compression methods, as the spatial quality is affected by the optical distortion of capturing…
Fast Block Structure Determination in AV1-based Multiple Resolutions Video Encoding
Bichuan Guo, Yuxing Han, Jiangtao Wen
The widely used adaptive HTTP streaming requires an efficient algorithm to encode the same video to different resolutions. In this paper, we propose a fast block structure determin…
Convex Optimization Based Bit Allocation for Light Field Compression under Weighting and Consistency Constraints
Bichuan Guo, Yuxing Han, Jiangtao Wen
Compared with conventional image and video, light field images introduce the weight channel, as well as the visual consistency of rendered view, information that has to be taken in…
A Bayesian Approach to Block Structure Inference in AV1-based Multi-rate Video Encoding
Bichuan Guo, Xinyao Chen, Jiawen Gu +2
Due to differences in frame structure, existing multi-rate video encoding algorithms cannot be directly adapted to encoders utilizing special reference frames such as AV1 without i…
