| Abstract | The quantization of block DCT coefficients is too coarse, and will result in much non-uniform artifacts, therefore, blocking and ring artifacts are usually visible in reconstructed video frames especially when the bitrate is not sufficient. In this paper, we present an adaptive perceptual preprocessing (APP) method to reduce the probability of these artifacts generated in video encoding. The APP algorithm employs a novel filter based on just noticeable distortion filter (JNDF) and adaptive bilateral filter (ABF), and they can be adaptively chosen by block characteristics and quantization parameters. Experimental results demonstrate our proposed algorithm can significantly improve the subjective quality of reconstructed image. ? 2016 IEEE. |
