Abstract
Official abstract text for this publication.
One embodiment is a method for selecting and grouping key points extracted by applying a feature detector on a scene being analyzed. The method includes grouping the extracted key points into clusters that enforce a geometric relation between members of a cluster, scoring and sorting the clusters, identifying and discarding clusters that are comprised of points which represent the background noise of the image, and sub-sampling the remaining clusters to provide a smaller number of key points for the scene.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for selecting and grouping key points extracted by applying a feature detector on a scene being analyzed, the method comprising: grouping the extracted key points into clusters that enforce a geometric relation between members of a cluster; scoring and sorting the clusters based on the density of the key points in the clusters; identifying and discarding clusters that are comprised of key points which represent the background noise of the image…
