A Quantitative Approach To The Temporal Dependency in Video Coding
Jingning Han, Paul Wilkins, Yaowu Xu +1
Motion compensated prediction is central to the efficiency of video compression. Its predictive coding scheme propagates the quantization distortion through the prediction chain an…
Study On Coding Tools Beyond Av1
Xin Zhao, Liang Zhao, Madhu Krishnan +5
The Alliance for Open Media has recently initiated coding tool exploration activities towards the next-generation video coding beyond AV1. With this regard, this paper presents a p…
A Technical Overview of AV1
Jingning Han, Bohan Li, Debargha Mukherjee +12
The AV1 video compression format is developed by the Alliance for Open Media consortium. It achieves more than 30% reduction in bit-rate compared to its predecessor VP9 for the sam…
Multi-Reference Video Coding Using Stillness Detection
Di Chen, Zoe Liu, Yaowu Xu +2
Encoders of AOM/AV1 codec consider an input video sequence as succession of frames grouped in Golden-Frame (GF) groups. The coding structure of a GF group is fixed with a given GF…
