This is a disctription of Aurélie Bugeau’s research in object detection. “First, groups of pixels having similar motion and photometric features are extracted. For this first step only a sub-grid of image pixels is used to reduce computational cost to improve robustness to noise. The grid is regularly spread on the image. Each of its pixel is described by its position, motion and color. We introduce the use of p-value to validate optical flow estimates. An iterative algorithm for automatic bandwidth selection has been introduced (more) in order to apply a parameter free mean shift clustering algorithm. “
