A frame-level rate control approach for stereoscopic video coding based on an exponential model

摘要

To investigate the impact of rate distortion on stereoscopic video coding and transmission, a new rate control approach based on exponential model is presented. The proposed rate control algorithm is performed on three levels: stereoscopic group of pictures (SGOP) level, stereoscopic image pair level and frame level. In frame level, the best quantization parameters pair is calculated based on exponential model and the binocular psycho-visual redundancy is utilized to allocate bitrates for the left and right frames. Experimental results show that the proposed method can efficiently control the bitrates, and it has better performance on rate distortion compared with the fixed quantization parameter method.
