EDGE NEIGHBORHOOD DESCRIPTOR
First Claim
1. System for generating an edge neighborhood descriptor for describing the surrounding of an interest point according to the closest edges, the system comprising:
- a sector determiner for determining N sectors, surrounding said interest point;
a closest edge determiner, coupled with said sector determiner, for determining for each of said N sectors, the edge pixel closest to said interest point, according to at least one binary edge map;
an edge neighborhood descriptor constructor coupled with said closest edge determiner, for constructing said edge neighborhood descriptor such that the length of the radius of each of said N sectors is determined according to at least the distance from said interest point to the edge pixel closest to said interest point within said sector, wherein said edge neighborhood descriptor includes said N sectors.

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.
