An Efficient Hierarchical Video Coding Scheme Combining Visual Perception Characteristics [PDF]

The Scientific World Journal, 2014
Different visual perception characteristic saliencies are the key to constitute the low-complexity video coding framework. A hierarchical video coding scheme based on human visual systems (HVS) is proposed in this paper.

Video analytical coding: When video coding meets video analysis [PDF]

Signal Processing: Image Communication, 2018
Leveraging on the properties of human visual system, most of the well-designed video coding standards utilize rate–distortion optimization techniques by maximizing a fidelity cost function (e.g., peak signal noise ratio, PSNR) under an available bit rate budget constrain.

Performance Evaluation of the Codec Agnostic Approach in MPEG-I Video-Based Point Cloud Compression

IEEE Access, 2021
In this study, we evaluated the codec agnostic approach of video-based point cloud compression (V-PCC) by applying several video codecs to V-PCC. The main concept of V-PCC is to use a video codec to compress the 2D patch images generated from a 3D point ...
