Advanced residual prediction (ARP) is an efficient tool for 3D video coding by exploiting the residual correlation between views. In ARP, the residual predictor could be efficiently produced by aligning the motion information at the current view for motion compensation in the reference view. On the other hand, such on-the-fly residual predictor derivation process increases the complexity significantly...
In recent years, video applications on handheld devices became more and more popular. Due to limited computational capability and power supply in handheld devices, rate-complexity-distortion optimization (RCDO) algorithms at encoder side draw increasing attention. The target of RCDO is to obtain the best rate-distortion (R-D) performance under a constraint of complexity. Generally, there are three...
To objectively evaluate the coding efficiency of video codecs, Bjøntegaard Delta PSNR (BD-PSNR) was proposed. Based on the rate-distortion (R-D) curve fitting, BD-PSNR is able to provide a good evaluation of the R-D performance. However, BD-PSNR has a critical drawback: It doesn't take the coding complexity into account. Clearly for practical video applications, especially for those on handheld devices,...
