In this article, a new CTU-level bit allocation scheme aimed at subjectively optimized video coding for video conferencing applications is presented, in which the non-cooperative Stackelberg game is used for formulating and solving the bit allocation

Region of interest (ROI) coding is a feature of prominent image coding systems that enables the specification of different coding priorities to certain regions of the image. JPEG2000 provides ROI coding through two mechanisms: either modifying wavele

The traditional region of interest coding method mainly uses low-level features to detect the Region of Interest (ROI). The ROI detected by it is poor in stability and is not easily interfered by noise. In this paper, ROI detection is performed on th

We introduce Region-of-Interest (ROI) coding for point cloud attributes, using an input-weighted distortion measure where the weights are determined by the ROI. In terms of coding, we use the Region Adaptive Hierarchical Transform (RAHT), which relie

This paper proposes a novel functionality in wavelet-based irregular mesh coding, which is interactive region-of-interest (ROI) support. The proposed approach enables the user to define the arbitrary ROIs at the decoder side and to prioritize and dec

Region of Interests (ROI) coding has shown advantages in subjectively optimized video coding. In this paper, we propose a new CTU-Ievel rate allocation scheme based on the Stackelberg Game model to enhance the visual quality of ROI which formulates t
