Attribute Compression of 3D Point Clouds Using Laplacian Sparsity Optimized Graph Transform
Yiting Shao, Zhaobin Zhang, Zhu Li +2
3D sensing and content capture have made significant progress in recent years and the MPEG standardization organization is launching a new project on immersive media with point clo…
Robust Emotion Recognition from Low Quality and Low Bit Rate Video: A Deep Learning Approach
Bowen Cheng, Zhangyang Wang, Zhaobin Zhang +5
Emotion recognition from facial expressions is tremendously useful, especially when coupled with smart devices and wireless multimedia applications. However, the inadequate network…
Co-projection-plane based 3-D padding for polyhedron projection for 360-degree video
Li Li, Zhu Li, Xiang Ma +2
The polyhedron projection for 360-degree video is becoming more and more popular since it can lead to much less geometry distortion compared with the equirectangular projection. Ho…
An Efficient Four-Parameter Affine Motion Model for Video Coding
Li Li, Houqiang Li, Dong Liu +4
In this paper, we study a simplified affine motion model based coding framework to overcome the limitation of translational motion model and maintain low computational complexity.…
Projection based advanced motion model for cubic mapping for 360-degree video
Li Li, Zhu Li, Madhukar Budagavi +1
This paper proposes a novel advanced motion model to handle the irregular motion for the cubic map projection of 360-degree video. Since the irregular motion is mainly caused by th…
