摘要：
Due to limited computational capability in handheld devices, complexity constrained video coding draws great attention in recent years. In this paper, a complexity scalable mode decision algorithm is proposed for complexity control of HEVC. First, complexity is properly mapped to a target in terms of prediction modes. Then a mode decision algorithm is proposed through statistics to get the optimal mode combination for each target complexity. Experimental results show that the proposed algorithm achieves a very large complexity control range of 10%-100% while maintaining good Rate-Distortion performance. For lowdelayP condition, an average gain of 1.1 dB in BDPSNR is obtained for 22 sequences when the complexity is around 20%.
