Abstract

The estimation of end-to-end distortion plays a key role in error-resilient video coding and perceptual quality control. The traditional end-to-end distortion estimation methods are mainly based on the MSE or MAD values, which sometimes poorly reflect subjective perception. This paper proposes a novel method to model the end-to-end quality degradation based on the SSIM index. Using factors extracted from the encoder, we build the models by considering the source distortion, the error-propagated distortion and the error-concealment distortion. These models can be used in joint source-channel coding with rate-distortion optimization as well as error-resilient video coding based on perception.
