VIEWER FOR OPTICAL FLOW THROUGH A 3D TIME SEQUENCE

摘要

A three-dimensional viewing technique that allows an operator to visualize the result of optical flow analysis through a sequence of images. The technique builds a track representing the movement of each feature point in a sequence of images and furthermore builds such a track for each feature point, to sub-pixel accuracy as desired. The tracks are are displayed in a 3D coordinate system whereby the x and y coordinates correspond to the coordinates of the feature in the image coordinate system and the z coordinate is a number associated with the temporal ordering of each image in the sequence. The resulting track display represents the evolution of the optical flow over time.
