NEAR-DUPLICATE IMAGE DETECTION
First Claim
Patent Images
1. A method for near-duplicate image detection performed by a physical computing system, the method comprising:
- applying a feature detection function to a number of images, a feature being defined by a geometric shape;
comparing characteristics of said geometric shapes defining said features from at least two of said number of images; and
characterizing said at least two of said number of images as a near-duplicate match if a predetermined percentage of said features of said at least two images match.

Abstract
A system and a method for near-duplicate image detection performed by a physical computing system includes applying a feature determining function to a number of images, a feature being defined by a geometric shape, comparing characteristics of said geometric shapes defining said features from at least two of said number of images, and characterizing said at least two of said number of images as a near-duplicate match if a predetermined percentage of said features of said at least two images match.

15. A method for near-duplicate image detection performed by a physical computing system, the method comprising:
-
applying a feature detection function to a number of images, a feature being defined by an ellipse; comparing characteristics of said ellipse; and characterizing at least two of said number of images as near-duplicate matches if a predetermined percentage of said features of said at least two of said number of images match; in which features are classified as a match if values of said characteristics of said ellipses are within a predefined tolerance range.
