A system and method for finding edge orientation and magnitude, and extracting a road path from an image. An image (4) is segmented into at least a first window and a second window. A first road segment having plural parameters within the first window is specified. Plural road segments are identified (6), each having plural parameters, in the second window. The orientation of plural line segments in the second window are determined (6), and paired (6), based on their orientation. The line segment orientations are determined by receiving a plurality of edge orientation estimates (8), transforming a portion of them (6), and aggregating the transformed portion (6) into an edge orientation estimate. A stochastic process is performed (6) on the plural parameters of the plural road segments to identify a second road segment having the maximum correlation with the plural parameters of the first road segment. |
