In order to meet the real-time video coding in embedded system and mobile device,a scalable complexity-distortion optimal motion estimation algorithm is proposed.The proposed algorithm can realize the computational complexity scalability of video encoder by adjusting complexity control parameters,and it can get the best video quality and obtain the relative optimal balance between the coding efficiency and distortion.Experimental results show that the proposed method can adjust the computational complexity of the encoder automatically according to the change of the processor's computation ability.It can reduce the calculation expenses of motion estimation greatly,with less performance degradation and bit-rate increase.
