λ-Domain Perceptual Rate Control for 360-Degree Video Compression.
IEEE Journal of Selected Topics in Signal Processing（2020）
摘要
The 360-degree video is projected to 2-D formats using various projection methods for efficient compression. As a necessary part of general-video compression, rate control is also indispensable for the projected 360-degree video compression. However, the current rate control algorithm has not been optimized for the 360-degree video compression yet. The Coding Tree Unit (CTU) level bit allocation i...
