Methods and apparatus for object recognition
First Claim
1. A method for recognizing an object of interest in a processing system, the method comprising:
- creating at least one image model based at least in part on at least one sample image;
receiving an input image of said object;
extracting at least one signature feature from said input image;
determining a set of candidate models based at least in part on filtering out any image model that does not contain said at least one extracted feature;
forming a sample image template based at least in part on a candidate model;
recognizing the object of interest based at least in part on comparing said input image to said sample image template.

Abstract
A processing system is provided that detects an object of interest. The system receives an input image of the object. At least one feature is extracted from the input image. The extracted feature is then used to determine a set of candidate models by filtering out image models that do not contain the extracted feature. A sample image template is then formed based on a candidate sample image. The object of interest is then detected by comparing the input image to the sample image template. In a preferred embodiment, the formation of the template further includes calculating a parameter, such as direction, expression, articulation or lighting, of the object.
