摘要：

Recently, foveated video has been introduced as an important emerging method for very low bit rate multimedia applications [1][2]. In this paper, we develop several rate control algorithms, and measure the performance of foveated video. We utilize H.263 video, and compare the performance with regular video based on the SNRC (signalto-noise ratio in curvilinear coordinates). In order to maximize compression, we use a maximum quantization parameter (QP = 31) for the regular video, and code a foveated video sequence at the equivalent bit rate. In simulation, we improve the PSNRC to 3.64 (1.62)dB under 30 (14) Kbits/sec for P pictures in CIF "News" ("Akiyo") standard video sequence.
