Based on the features of infrared image and the speciality of fractal dimension,a method of detection infrared dim small target based on fractal dimension was presented.Using a window slide on the infrared image, the fractal dimension of the window can be calculated and denoted as the fractal dimension of the center pixel of the window.Construct an image using the fractal dimension of each pixel.Target can be detected by properly selecting threshold due to the different values between target and background ...
