Abstract: License plate recognition techniques have been successfully applied to the management of stolen cars, management of parking lots and traffic flow control. This study proposes a license plate based strategy for checking the annual inspection standing of motorcycles from images taken on the wayside and at selected inspection stations. Both a UMPC (Ultra Mobile Personal Computer) with a web camera and a desktop computer are used as hardware platforms in this paper a survey is being carried out in the field of Automatic license plate localization. Automatic license plate recognition (ALPR) is to extract vehicle license plate information from an image or a sequence of images. The extracted info can be used with or without a database in many applications like electronic payment systems, freeway and specific road observation systems for traffic surveillance.
