Abstract :
An improved method for the TZSearch fast motion estimation algorithm in the Joint Multi-view Video Coding (JMVC) is proposed in this work. It is based on early terminating the calculation of Sum of Absolute Difference (SAD) and increasing the number of predicted motion vectors to reduce the inter-view redundancy and save the encoding time. Experimental results show that the proposed method has much more reduction in encoding time than the original TZSearch method in the JMVC, under the conditions of the encoding bit-rate and Peak Signal to Noise Ratio (PSNR) barely changed.
