Color difference weighted adaptive residual preprocessing using perceptual modeling for video compression
作者:
Highlights:
• We investigate a method for video compression using a human visual system model.
• We use color appearance, saliency, and spatial activity information from the scene.
• The method has been implemented in the JM 18.0 H.264/AVC encoder reference software.
• Significant improvements in compression are obtained without perceptible degradation.
• The imperceptibility of the changes was confirmed through psychophysical evaluation.
