Abstract :
We propose a perceptually-adaptive motion compensated temporal filtering (MCTF) method to enhance the visual quality of 3D wavelet video coding schemes with spatial-domain MCTF. In our scheme, a spatio-temporal masking model in image domain is incorporated into the lifting structure of MCTF. The model is used to guide the motion search and the prediction step in MCTF so as to remove the visual redundancy in the video sequence. Experimental results show that the proposed scheme can significantly improve the visual quality of decoded video at different bitrates
