Abstract
In this paper, an efficient rate-prediction technique using the wavelet-based activity measure is proposed which can be successfully used for video rate-control. Experimental results show that the proposed prediction-based rate control scheme can regulate the bit-rate under dramatic scene changes more effectively and achieve better PSNR performance than the TM5 rate control mechanism.
