This paper puts forward a new shadow defects segmentation method based on YCbCr color space. First, Mean Shift smoothing method is used to smooth the image pixels, and the motion area which includes the vehicle and the shadow defect is selected by binary discrete wavelet transforms after Mean Shift smoothing, and then the original data of the shadow defect according to the characteristics of the occurrence...
Although recognition of vehicle license plate is well studied, characters can be obscured by color stains due to rust, mud, peeling paint or fading colors and become unrecognizable. In this paper, two approaches are presented to remove stains from license plate images by using photometric stereo technique and hole filling algorithm of texture synthesis respectively. The former method extracts height...
