Abstract
A system having an approach for prioritizing targets for an order of capturing the targets photographically or otherwise. Prioritizing is based on cost of obtaining or capturing the target for viewing or photographing in high resolution. One acquisition mechanism is for obtaining a wide field of view of a scene of targets and another acquisition mechanism is for obtaining a narrow field of view of a target for capture. The cost for prioritizing is based on the time that the narrow field of view acquisition mechanism takes to pan and tilt to get a close-up image of a target divided by the width of the target. The targets may be faces of people.
Claims19
A face acquisition system comprising:
- a processor comprising a target prioritizer;
- a wide field of view acquisition mechanism connected to the processor;
- and
- a narrow field of view acquisition mechanism connected to the processor;
- wherein the wide field of view acquisition mechanism is for observing a plurality of faces of people;
- and
- wherein the target prioritizer is for prioritizing the plurality of faces as to which face should be captured on image in a numerical order.
A method for tracking faces, comprising:
- observing a plurality of people with a wide field of view acquisition mechanism;
- prioritizing faces of the plurality of people according to cost;
- capturing a first face with having a least cost with a narrow field of view acquisition mechanism;
- and
- capturing a second face having the least cost after capturing the first face;
- and
- wherein:
- when a face is captured, that face is removed from the faces of the plurality of people, to be prioritized;
- cost of a face is the cost of capturing the face.
A system for capturing faces, comprising:
- a wide field of view acquisition mechanism;
- a pan/tilt narrow field of view acquisition mechanism;
- and
- a processor for prioritizing faces for capture, connected to the wide field of view acquisition mechanism and the pan/tilt narrow field of view acquisition mechanism:
- wherein prioritizing faces for capture is based on a cost of acquisition for an image of a face having a standard resolution.
