Abstract

We present a perceptually-adaptive in-band preprocessing scheme for 3-D wavelet video coding. In our scheme, after the original video is decomposed by 2-D spatial wavelet transform, a preprocessor is incorporated to remove some visually insignificant wavelet coefficients (noise-like) before the motion compensated temporal filtering of each spatial subband. The preprocessing process is guided by a wavelet domain just-noticeable-distortion profile, which locally adapts to spatial wavelet transform coefficients. Experimental results show that the proposed scheme can efficiently enhance the visual quality of coded video with the same objective quality at different bitrates.
