Abstract: We present techniques for improving the speed of robust motion estimation based on random sampling of image features. Starting from Torr and Zisserman's MLESAC algorithm, we address some of the problems posed from both practical and theoretical standpoints and in doing so allow the random search to be replaced by a guided search. Guidance of the search is based on readilyavailable information which is usually discarded, but can significantly reduce the search time. This guided-sampling... (Update)

...point x j to evaluate the veracity of the proposed projection. Rather than choosing the four samples at random, recent extensions [17] to Torr and Zisserman s MLESAC algorithm [18] are used to provide guided sampling and consensus. Under the hypothesis that the motion...
.... However, it has been observed experimentally that RANSAC runs much longer (even by an order of magnitude) than theoretically predicted [29]. The discrepancy is due to one assumption of RANSAC that is rarely true in practice: it is assumed that a model with parameters computed...
