Optical Flow Computation Based on Bayesian Selecting Scheme
《Chinese Journal of Electronics》2007年第1期107-110,共4页LU Zongqing XIE Weixin PEI Jihong 
Dense optical flow schemes are challenged by the presence of motion boundaries. In state of the art optical flow approaches, over-smoothing of motion boundaries accounts for most of the error. A new optical flow estim...
