Abstract
A method of determining a vanishing point related to an image, the method includes the steps of: detecting line segments in the image; determining intersections from pairs of line segments; assigning a probability to each intersection of the pairs of line segments; determining a local maximum corresponding to a plurality of probabilities; and outputting an estimated vanishing point vector &ngr;E that corresponds to the determined local maximum such that an estimated location of the vanishing point about the estimated vanishing point vector &ngr;E results.
