Abstract:
In vehicles detection problem of video images, the vehicle cannot be extracted correctly due to the existence of the shadow, which results in low reliability in intelligent transportation system. In this paper, a method is proposed to remove the vehicle shadow by using the pixel gray distribution features of shadow. According to the theory of shadow generation, the pixel distribution of shadows can be obtained by projecting the moving target from four directions. By using the pixel shadow curve, the distribution characteristics were calculated. Deriving the range of probability distribution is just the shadow part allows the shadow to be removed.. The experimental results showed that this method could remove vehicle cast shadows in the image quickly and accurately.
