Taming the Irregular Shape Problem
Devices that perform well under laboratory conditions often face hurdles in uncontrolled real-world situations. This is true for charge-coupled devices (CCDs) and thermal cameras used in machine vision applications where an object's shape, location and orientation vary. Often the culprit is the detector array. If we were to estimate the output of a CCD or thermal camera, we would typically draw an image over the detectors, aligning the image with the detector axes. We show it this way because...
