Type and shape of the car is coherent

one type of the car possess the one and only shape. Based on this fact

instead of recognition of the type of the car

recognition of the shape of the car is discussed detailed in this paper. Considering that a few methods proposed in the correlate paper are not accurate and those methods are lack of gracefulness

matrix singular value method is used in car shape recognition in this paper. As one of algebraic characters of matrix

singular value is reported to be used in image recognition

such as human face recognition

but the report about the method used in recognition of the vehicle shape has not been accessible. In order to standardize the different weight of the images in the same sites owing to different light

gray level rectified factor is put forward. At last

quantitative and qualitative analysis about the methods is proposed.
