Abstract :
This letter proposes a distributed video coding (DVC) scheme based on the human visual system (HVS). As we know, HVS can seldom sense any changes below the just-noticeable-difference (JND) distortion threshold due to its underlying sensitivity and masking property. Therefore, the un-noticeable signal differences between the original frame and side information need not to be corrected in DVC. Experimental results demonstrate that the proposed algorithm can save the bits-rates significantly without degrading the subjective quality of the reconstructed frames.
