Study of Name Plate Detection using Blob analysis Method

Abstract

Name Plate detection is the most interesting and challenging research topic from past few years. It is known that the size of a Name Plate is changing day by day. Some name plate is small in size and also in big size that’s create a problem in character recognition of Name and then separated individual character using Region prop algorithm. So we need an approach which is able to detect a particular Name Plate. In this paper we will discuss on Name Plate detection technique. An automated system is developed using morphological recognition algorithm in MATLAB R2013a. In which image is captured from camera and converted into gray scale image for pre-processing. After conversion, image complemented, binary conversion is applied on image. After conversion canny edge detection method has done and passed this detection to the dilation process. After filtration and dilation, area is selected where number of name plates is maximum and name plates are recognized from the image in the form of bounding box. Blob analysis is used for each name plate separately to detect name plate.
