Abstract

This paper presents an accurate bit rate and quality control algorithm for 3D multiview sequences. We remodel the quadratic rate-distortion model for 3D multiview sequences based on their picture types. The proposed method consists of two levels for more accurate bits rate control. In a frame level, it sets quantization parameters based on HVS (Human Visual System) and reduces error bits by remodeling rate-quantization. In a MB level, rate control is activated to provide stricter buffer regulations and higher bit rate encoding based on the target bits and the quantization parameters calculated at the frame level. The proposed algorithm shows improvements in rate control as well as in PSNR compared to the conventional methods. It also provides more accurate rate control and higher image quality than TM5 and TMN8 at various bits rates.
