Abstract
Methods and systems for automatic license plate recognition (ALPR) can involve obtaining results from a manual image review of an image captured by one or more ALPR cameras and processed by an ALPR engine and feeding the results from the manual image review back to the ALPR engine to train the ALPR engine where to search in the image for a license plate. Training of the ALPR engine increase the attach rate of an optical character recognition (OCR) engine with respect to images captured the ALPR camera(s) and processed by the ALPR engine.
