CONTROLLED HIGH RESOLUTION SUB-IMAGE CAPTURE WITH TIME DOMAIN MULTIPLEXED HIGH SPEED FULL FIELD OF VIEW REFERENCE VIDEO STREAM FOR IMAGE BASED BIOMETRIC APPLICATIONS

摘要

There is discloses a method and apparatus for image processing for object recognition applications. An image capture device is used to acquire a first, relatively low resolution image of a relatively wide field of view containing a plurality of objects. Apattern recognition algorithm is then applied to the first image so as to identify objects of interest, and at least one object of interest is selected from the first image and its coordinates within the image are determined. The determined coordinates are then used to control either the image capture device or an additional image capture device so as to obtain a sequence of second, relatively high resolution images of a relatively narrow field of view containing the at least one object of interest.
