1. A method of confidence estimation for optical flow comprising the steps of:
computing the census texture gradient (Cg) features for each pixel of an input image;
computing smoothened versions of said features (Sg);
constructing a feature vector for each pixel of the input image;
computing a classifier score from said features by employing a decision tree classifier;
converting the classifier score into a confidence score.
