IMAGE PROCESSING
First Claim
Patent Images
1. An image processing method comprising the steps of:
- partitioning an image under test to form a plurality of image segments, each segment representing a set of pixels having similar image properties, at least some segments being contiguous;
deriving feature data from a subset comprising one or more of the image segments;
comparing the feature data from the subset of image segments with feature data indicative of respective reference image segments so as to detect a degree of similarity between the image segments under test and the reference image segments.

Abstract
An image processing method includes partitioning an image under test to form a plurality of contiguous image segments having similar image properties, deriving feature data from a subset including one or more of the image segments, and comparing the feature data from the subset of image segments with feature data derived from respective image segments of one or more other images so as to detect a similarity between the image under test and the one or more other images.
