“…In [13], a novel FMD is proposed by exploiting the zero motion blocks and zero coefficient blocks to reduce the number of modes to be checked. A classification method is proposed in [14], where the mode in the first class (including SKIP and INTER16×16) is first checked. Further mode checking would be performed depending on temporal layer indexes and whether all the resulted coefficients are zeros.…”

Various fast mode decision algorithms are proposed to reduce computational complexity for the H.264/scalable video coding standard. In this article, we focus on skip mode detection for coarse grain quality (CGS). We propose a fast skip mode detection approach by exploiting surrounding skip patterns, rate distortion (RD) cost and coded block pattern (CBP). Experimental results show that, with 0.589% BDBR and 0.011 dB BDPSNR loss on average, the proposed method achieves considerable encoding time reduction compared with the reference software. Compared with the state-of-the-art early skip algorithm, the proposed method also achieves 9.98% time reduction on average.
