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…

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…
