SCENE ANALYSIS
First Claim
Patent Images
1. A method of estimating the number of individuals in an image, the method comprising the steps of:
- (i) generating, for a plurality of image positions within at least a portion of a captured image of the scene, an edge correspondence value indicative of positional and angular correspondence with a template representation of at least a partial outline of an individual, and;
(ii) detecting whether image content at each of the image positions corresponds to at least a part of an image of an individual in response to said detected edge correspondence value.

Abstract
Apparatus is arranged in operation to perform a method of estimating the number of individuals in a scene. The method comprises generating, for a plurality of image positions within at least a portion of a captured image of the scene, an edge correspondence value indicative of positional and angular correspondence with a representation of at least a partial outline of an individual. Analysis of the edge correspondence value is used to detect whether each of the plurality of image positions contributes to at least part of an image of an individual.

23. A data processing apparatus, arranged in operation to estimate said number of individuals in a scene, said apparatus comprising;
-
an analyser operable to generate, for a plurality of image positions within at least a portion of a captured image of said scene, an edge correspondence value indicative of positional and angular correspondence with a template representation of at least a partial outline of an individual, and logic operable to detect whether image content at each of said image positions corresponds to at least a part of an image of an individual in response to said detected edge correspondence value. - View Dependent Claims (24, 25, 26, 27, 29, 31, 33)
