In this paper the text found on the vehicle plates is detected from the input image and this requires the\udlocalization of number plate area in order to identify the characters present on it. In this work, simple color\udconversion edge detection and connector measurement technique with the application of median filter as\udone of the operators is attempted. This paper presents an approach using simple but efficient\udmorphological operations, filtering and finding connected components for localization of Indian number\udplates. The algorithm has been tested on 100 samples and is found to extract both alphabets and numbers\udfrom vehicle license plates images with an accuracy of 93% for both two and four wheeler license plates of\udChennai regio
