摘要

PROBLEM TO BE SOLVED: To provide a technique having high identification performance without needing previous sectionalization in relation to a method for detecting and localizing an object (structure) in a two-dimensional image.

SOLUTION: This method for representing an image comprises processing the image to produce a second image highlighting edges in the image (e.g. a gradient image) and deriving a descriptor based on spatially integrated or rotationally invariant representations of regions of the second image.
