Matching based on local brightness is quite limited, because small changes on local appearance invalidate the constancy in brightness. The root of this limitation is its treatment regardless of the information from the spatial contexts. This papers leaps from brightness constancy to context constancy, and thus from optical flow to contextual flow. It presents a new approach that incorporates contexts to constrain motion estimation for target tracking. In this approach, one individual spatialdoi:10.1109/cvpr.2009.5206719 dblp:conf/cvpr/WuF09 fatcat:raegxjhraffr3m4sndmc3zucbu
