FACE DETECTION AND TRACKING IN A WIDE FIELD OF VIEW
First Claim
1. A facial detection and tracking system, comprising:
- a wide field of view camera for detecting one or more objects located within a wider field of view; and
at least one narrower field of view camera for obtaining a higher-resolution image of at least one detected object, each narrower field of view camera adapted to cover a subset space of the wider field of view.

Abstract
Facial detection and tracking systems and methods within a wide field of view are disclosed. A facial detection and tracking system in accordance with an illustrative embodiment of the present invention can include a wide field of view camera for detecting and tracking one or more objects within a wider field of view, and at least one narrower field of view camera for obtaining a higher-resolution image of each object located within a subset space of the wider field of view. The wide field of view camera can be operatively coupled to a computer or other such device that determines the subset space location of the individual within the wider field of view, and then tasks one or more of the narrower field of view cameras covering the subset space location to obtain a high-resolution image of the object.

40. A facial detection and tracking system, comprising:
-
a wide field of view camera adapted to continuously operate in a wide-angle mode for detecting one or more objects located within a wider field of view;
a plurality of narrower field of view cameras for obtaining a higher-resolution image of each detected object, each narrower field of view camera adapted to cover a subset space of the wider field of view; and
processing means for processing images received from the wide field of view camera and the narrower field of view cameras.

41. A facial detection and tracking system, comprising:
-
a wide field of view camera for detecting and tracking one or more individuals located within a wider field of view; and
at least one narrower field of view TBI camera for obtaining a higher-resolution image of each tracked individual, each TBI camera being adapted to cover a subset space of the wider field of view. - View Dependent Claims (42, 43)

44. A method for detecting and tracking an object within a wide field of view, comprising the steps of:
-
detecting an object within the wider field of view using at least one wide field of view camera;
determining the subset space location of the object;
tasking one or more narrower field of view cameras covering the subset space location to scan one or more higher-resolution images of the object; and
processing the images received from the one or more narrower field of view cameras to obtain at least one parameter relating to the object. - View Dependent Claims (45, 46, 47, 48, 49)

50. A method for facially detecting and tracking one or more individuals within a wide field of view, comprising the steps of:
-
detecting an individual within the wide field of view using at least one wide field of view camera;
determining the subset space location of the individual;
tasking one or more narrower field of view TBI cameras covering the subset space location to perform a low band and high band near-IR scan of the individual'"'"'s face;
subtracting and fusing the high near-IR image from the low near-IR image;
performing a multi-band feature extraction routine to detect one or more facial features of the individual; and
processing the images to obtain a final video facial image. - View Dependent Claims (51, 52)
