Rate control model for high dynamic range video

This paper describes a luminance based rate control (RC) model for high dynamic range (HDR) video. A novel mathematical relationship between luminance and bit allocation of a coding tree unit (CTU) is presented. By adjusting the existing RC algorithm …

Weight-based bit allocation scheme for VR videos in HEVC

Since VR videos shown on the head-mounted display (HMD) is omnidirectional, the average distortion of VR videos in all directions shall be calculated in spherical domain. Several metrics have been proposed to calculate the coding loss of VR videos in …
