Fixation driven contour completion with angular ordering

The paper presents a technique for grouping edges around a given visual fixation point. By giving the fixation point and a starting position, the edge grouping problem becomes a sequential search, and can be efficiently implemented with dynamic programming. By providing multiple fixation points, the method can explore the scene in a more flexible and context driven manner. The paper proposes a method for automatically selecting starting positions of the search and a method to extract salient contours successively at different scales.
