Recently, the problem of binarization in night surveillance image using IR-LED(InfraRed-LED) is an issue because the same object has different intensity in the image according to the distance between camera and the object. This paper introduces a new local thresholding technique based on the relative intensity of IR-LED that is acquired with the camera and installation informations.
