Multimedia devices are weeding out the old and bringing forth the new constantly, so the demand for image quality are increasing. The common used video compression standard H.264/AVC was inadequate, a new generation of video compression standard HEVC is substantially improving H.264. HEVC has improved video quality and compression ratio, but the coding complexity also increases a lot. In this thesis, we proposed a fast inter-mode decision algorithm for HEVC, we utilize the number of zero-blocks and distribution in CU / PU to simplify the mode by detecting the probability distribution mode earlier, and to simplify the computational complexity by detecting TU size probability distributions. Finally, we combine two algorithms to achieve the purpose of accelerating the encoding procedure. According to the experimental results, our proposed algorithm can achieve 62.22% of time saving on average while maintaining coding performance. |
