Face or Other Object Detection Including Template Matching
First Claim
Patent Images
1. A digital image acquisition device, comprising:
- an optoelectonic system for acquiring a digital image;
a processor; and
a template matching module configured to program the processor to apply multiple differently-tuned object detection classifier sets in parallel to the digital image to determine one or more of an object type, configuration, orientation, pose or illumination condition, and to dynamically switch between object detection templates to match a determined object type, configuration, orientation, pose, blur, exposure or directional illumination condition, or combinations thereof.

Abstract
A template matching module is configured to program a processor to apply multiple differently-tuned object detection classifier sets in parallel to a digital image to determine one or more of an object type, configuration, orientation, pose or illumination condition, and to dynamically switch between object detection templates to match a determined object type, configuration, orientation, pose, blur, exposure and/or directional illumination condition.
