Abstract
System for generating an edge neighborhood descriptor for describing the surrounding of an interest point according to the closest edges includes a sector determiner, a closest edge determiner, and an edge neighborhood descriptor constructor, the closest edge determiner is coupled between the sector determiner and the edge neighborhood descriptor constructor. The sector determiner determines N sectors, surrounding the interest point. The closest edge determiner determines for each of the N sectors, the edge pixel closest to the interest point, according to at least one binary edge map. The edge neighborhood descriptor constructor constructs the edge neighborhood descriptor such that the length of the radius of each of the N sectors is determined according to at least the distance from the interest point to the edge pixel closest to the interest point within the sector, the edge neighborhood descriptor includes the N sectors.
