TLDR
It is shown that the proposed optimization scheme can reduce the coding computing complexity while the degradation of visual quality is almost negligible.Abstract:
H.264 is well known for the best compression performance with high computational complexity. In order to be more viable in computationally constraint environments, it needs a performance optimization scheme, proposed in the paper based on trade-off between the computational complexity and distortion. Computationally intensive modules are empirically identified and analyzed in terms of computational complexity and distortion in the H.264 video coding framework. Operating modes are extracted in the complexity-distortion space through an exhaustive search. It is shown that the proposed optimization scheme can reduce the coding computing complexity while the degradation of visual quality is almost negligible.read more

Motion-compensating prediction with fractional-pel accuracy
TL;DR: A three-state technique for reliable displacement estimation with fractional-pel accuracy is introduced, based on phase correlation, and for motion-compensation with block size of 16 pels*16 pels, 1/4- Pel accuracy appears to be sufficient for broadcast TV signals, whereas for videophone signals,1/2-pel Accuracy is desirable.
