H.264 Deblocking Speed-up Using Hybrid Optimization Technique

The proposed method defines the problem of reducing the complexity of H.264 decoding. Since deblocking accounts for a significant percentage of H.264 decoding time. Observing that branch operations are costly and that in the deblocking process there are events with significantly high probability of occurrence. The idea of Hybrid optimization to speed up the boundary strength derivation and the true-edge detection by taking advantage of the biased statistical distribution is applied. The proposed techniques can reduce the deblocking computation time, while maintaining the bit-exact output. KeywordsDeblocking, H.264 Decoding, Boundary Strength, Optimization
