For example, -b 20 means clip the flow value beyond [-20, 20] and maps the [-20, 20] interval to [0, 255] in grayscale image space. 5 seconds on an NVIDIA R TeslaTM C2050 GPU for the proposed parameters, which is a factor 6 faster than the TV-L1-improved algorithm (cf. The computation time for the optical ow between a pair of 640 480 RGB images is around 0. This is A Duality Based Approach for Realtime TV-L1 Optical Flow. The class implements the "Dual TV L1" optical flow algorithm described in [319] and [240] . By definition, the optical flow is the vector field (u, v) verifying image1 (x+u, y+v) = image0 (x, y), where (image0, image1) is a couple of consecutive 2D frames from a sequence. Zach, T.
