Abstract
An apparatus and method for automatic character recognition is presented ch automatically locates and recognizes alphanumeric characters in a scene viewed by a raster-scan type of sensor. By this method the apparatus can search the entire scene and recognize up to seven alphanumeric characters in a bounded area of known size by the correlation technique in less than 1.5 seconds. The technique used first locates the bounded area and alphanumeric characters and then performs the recognition. Two different feature extraction methods are used to locate the characters in the scene. The recognition function is performed by correlation using an incoherent electrooptical processor.
