摘要：In this paper the text found on the vehicle plates is detected from the input image and this requires thelocalization of number plate area in order to identify the characters present on it. In this work, simple colorconversion edge detection and connector measurement technique with the application of median filter asone of the operators is attempted. This paper presents an approach using simple but efficientmorphological operations, filtering and finding connected components for localization of Indian numberplates. The algorithm has been tested on 100 samples and is found to extract both alphabets and numbersfrom vehicle license plates images with an accuracy of 93% for both two and four wheeler license plates ofChennai region.
