Abstract (en)
[origin: WO9721188A1] A recognition system which obtains and analyzes images of at least one object in a scene comprising a wide field of view (WFOV) imager (10, 12) which is used to capture an image of a scene and to locate the object and a narrow field of view (NFOV) imager (14) which is responsive to the location information provided by the WFOV imager and which is used to capture an image of the object (56), the image of the object having a higher resolution than the image captured by the WFOV imager is disclosed. In one embodiment, a system that obtains and analyzes images of the irises of eyes of a human or animal in an image with little or no active involvement by the human or animal is disclosed. A method of obtaining and analyzing the images of at least one object in a scene comprising capturing a wide field of view image of the object to locate the object in the scene; and then using a narrow field of view imager responsive to the location information (54) provided in the capturing step to obtain a higher resolution image of the object is also disclosed.
