Check out emgu.cv. It's an open source wrapper for opencv, an open source image analysis tool. Here is an example on how to use it to detect license plates.

My experience is fairly positive as for this just working. It catches the main cases 90% of the time or so I'd say.

The Canadian province of Quebec first required its residents to register their motor vehicles in 1906. Registrants provided their own licence plates for display until 1908, when the province began to issue plates.[1] Plates are currently issued by the Société de l'assurance automobile du Québec (Quebec Automobile Insurance Corporation).

From 1963 to 1977 (except 1967), licence plates carried the slogan La Belle Province ('The Beautiful Province'), a nickname for Quebec. Since 1978, they have carried Je me souviensPadaharella ammayi songs download 2017. ('I remember'), the official motto of the province.

Since 1979, Quebec legislation has required only rear plates, though there are certain cases where front plates are also required. Annual renewal stickers were used from 1979 to 1992; Quebec is currently one of three provinces where such stickers are not used (the others being Saskatchewan and Manitoba). Dates for renewals of plates on passenger vehicles are determined based on the first letter of the registered owner's surname, while for other vehicles they are determined based on the type of vehicle: for example, plates on passenger vehicles whose owners' surnames begin with the letter 'L' are to be renewed in September, as are school bus plates.[2] Registrations and fees may be renewed up to three months in advance. Trailer plates ('R' category) are not renewed annually: they are only registered upon initial purchase, or when transferred to another owner.[2] Enforcement is done by a variety of methods, including automated number plate recognition.[3]

Vehicles registered in Quebec can only display approved plates. Decorative designs are permitted at the front of the vehicles, but displaying foreign plates (or plates whose design is likely to be mistaken for a registration plate) is an offence under articles 34 and 56 of the Code de la sécurité routière (Road Safety Act) and punishable with a fine.[4]

Relief Design Inc., of St-Louis de Blandford, is specialized in the production of licence plates on behalf of the SAAQ.[citation needed]

Passenger baseplates[edit]

1908 to 1978[edit]

In 1956, Canada, the United States and Mexico came to an agreement with the American Association of Motor Vehicle Administrators, the Automobile Manufacturers Association and the National Safety Council that standardized the size for licence plates for vehicles (except those for motorcycles) at 6 inches (15 cm) in height by 12 inches (30 cm) in width, with standardized mounting holes.[8] The 1955 (dated 1956) issue was the first Quebec licence plate that complied with these standards.
