License plate recognition (LPR) is a technology that enables computer systems to read automatically the registration number (license number) of vehicles from digital pictures. This paper deals with the recognition of Indian car license plate recognition. The LPR system consists of four steps Plate Localization, Preprocessing, Segmentation and Normalization and Optical Character Recognition (OCR). Morphological operator is applied to the image to identify the plate location. Then the plate region is then preprocessed by applying the histogram equalization technique. The smearing and morphological algorithms are used to segment the characters and the segmented result is normalized and fed to the OCR part. The characters are then recognized using the template matching algorithm.
