System and method for finding saddle-point-like structures in an image and determining information thereof

摘要

This invention provides a system and a method for finding of features in images, which have structures saddle-point-like; for this purpose, mathematically relatively down-intensive processes are used, for example, consisting of a anti-correlation process anti-correlation kernel and the therewith connected to a plurality of pixel neighborhoods operates within the image. This process permits the rapid analysis of the combined picture is to any kind of features, which has saddle-point-like structures, by determining whether the anti-correlation kernel a weak or strong reaction at different positions within the image. The anti-correlation kernel, a strong reaction independently of the alignment of saddle-point-like structures. The examined anti-correlation process a plurality of pixel neighborhoods in the image, and takes place in this way all the structures saddle-point-like independently of their orientation, because of the process is angle-independent. The structures are then grouped and refined (for example, in a grid) in an endeavor id-topologies within the image, to find and to decode.
