Total Least Squares Estimation of Stereo Optical Flow

In this paper, we propose a new method for disparityassisted stereo optical ow estimation. This method is based on the linearization of the round-about compatibility constraint, which converts a stereo optical ow estimation problem to a single channel optical ow estimation problem. An over-determined system of optical ow equations can then be constructed for estimating the ow elds. Total least squares, instead of the traditional least squares is used to solve the estimation problem. We also investigate the extension of the locally constant ow model across the time domain. The experiments presented demonstrate that the proposed technique performs very well.
