Perceptually-friendly H.264/AVC video coding
Zhenzhong Chen, Christine M. Guillemot · 2009
This paper presents a perceptual H.264/AVC video coding method based on a foveated just-noticeable-distortion (JND) model. Since the perceptual acuity decreases with the increased eccentricity, a foveation model is adopted to further explore the perceptual redundancy in addition to the spatial and temporal just-noticeable-distortion models. Bit allocation and rate-distortion optimization algorithms based on the foveated model are addressed. The performance of the foveated JND model is assessed with subjective visual tests. Applying the proposed model in H.264/AVC video coding can achieve better visual quality.
