<P> There are diverse algorithms for traffic - sign recognition . Common ones are those based on the shape of the sign board . Typical sign board shapes like hexagons, circles, and rectangles define different types of signs, which can be used for classification . Other major algorithms for character recognition includes Haar - like features, Freeman Chain code, AdaBoost detection and deep learning neural networks methods . Haar - like features can be used to create cascaded classifiers which can then help detect the sign board characters . </P> <P> Deep learning can be incorporated into traffic - sign detection . Polygonal approximation of digital curves using Ramer--Douglas--Peucker algorithm can be used to detect the shape of the sign boards and methods like Support Vector Machines and Byte - MCT with an AdaBoost classifier has been used in one of the methods to detect traffic signs . </P> <Ul> <Li> Audi A8 </Li> <Li> BMW 7 Series </Li> <Li> BMW 5 Series Gran Turismo </Li> <Li> BMW 5 Series </Li> <Li> BMW 4 Series </Li> <Li> BMW 3 Series </Li> <Li> BMW 1 Series </Li> <Li> Citroën C3 </Li> <Li> Ford Focus </Li> <Li> Ford Edge </Li> <Li> Honda Civic </Li> <Li> Honda Accord </Li> <Li> Jaguar F - Pace </Li> <Li> Kia Sportage </Li> <Li> Lexus LS </Li> <Li> Mazda CX - 5 </Li> <Li> Mazda 3 </Li> <Li> Mazda 6 </Li> <Li> Mercedes - Benz E-Class </Li> <Li> Mercedes - Benz S - Class </Li> <Li> Mercedes - Benz SL - Class </Li> <Li> Nissan Micra </Li> <Li> Nissan Pulsar </Li> <Li> Nissan Qashqai </Li> <Li> Nissan X-Trail </Li> <Li> Opel / Vauxhall Insignia </Li> <Li> Renault Kadjar </Li> <Li> Renault Espace </Li> <Li> Renault Talisman </Li> <Li> Saab 9 - 5 </Li> <Li> Toyota Prius </Li> <Li> Volkswagen Phaeton </Li> <Li> Volvo S60 </Li> <Li> Volvo S80 </Li> <Li> Volvo S90 </Li> <Li> Volvo V40 </Li> <Li> Volvo V60 </Li> <Li> Volvo V70 </Li> <Li> Volvo V90 </Li> <Li> Volvo XC40 </Li> <Li> Volvo XC60 </Li> <Li> Volvo XC70 </Li> <Li> Volvo XC90 </Li> </Ul> <Li> BMW 7 Series </Li>
