Abstract
News editors obtained the following quote from the background information supplied by the inventors:“Embodiments of the invention relate to the field of image processing, and more specifically, to theprocessing of candidate strings resulting from optical character recognition performed on an image toidentify a match for a model string in the image.“Optical Character Recognition (OCR) generally refers to the mechanism of converting images of typed,handwritten or printed text into machine-encoded text (e.g., in an American Standard Code for InformationInterchange (ASCII) format), whether from a scanned document, a photo of a document, a photo of ascene (e.g., an image acquired by a surveillance camera including a license plate number) or from subtitletext in an image (e.g., closed captioning text). Generally, an OCR mechanism is a computer-implementedprocess that includes the steps of acquiring an image containing a string of characters to be recognized,recognizing individual characters in the input image as characters of an alphabet, segmenting the charactersinto one or more strings of characters, and performing a string correction or string recognition mechanismto return a corresponding output string of characters that corresponds to one or more model strings thatare searched for in the image (e.g., license plate numbers, serial numbers, postal codes, addresses, etc.).
