Vision is a natural tool for human-computer interaction, since it provides visual feedback to the user and mimics some human behaviors. It requires however the fast and robust computation of motion primitives, which remains a difficult problem. In this work, we propose to apply some recent mathematical results about convex optimization to the TV-L1 optical flow problem. At the cost of a small smoothing of the Total Variation (TV), the convergence speed of the numerical scheme is improved… CONTINUE READING
