Geo-Relevance for Images
First Claim
Patent Images
1. A method comprising:
- determining a plurality of image frustums having an approximate point of origin and an approximate direction, each of said image frustums being determined from an individual image;
arranging said plurality of image frustums based on said approximate point of origin and said approximate direction to form a relevance map;
determining a first area of relevance from said relevance map; and
identifying a first group of said plurality of images that include said first area of relevance.

Abstract
Images may be sorted and categorized by defining a frustum for each image and overlaying the frustums in two, three, or four dimensions to create a density map and identify points of interest. Images that contain a point of interest may be grouped, sorted, and categorized to determine representative images of the point. By including many images from different sources, common points of interest may be defined. Points of interest may be defined in two or three Euclidian dimensions, or may include a dimension of time.

10. A system comprising:
-
a frustum determination engine adapted to determine a frustum of an image comprising an approximate point of origin and an approximate direction; a mapping engine adapted to map a plurality of frustums onto a relevance map; and a grouping engine adapted to determine a first area of relevance from said relevance map and create a first group of images that include said first area of relevance. - View Dependent Claims (11, 12, 13, 14, 15, 16)
