Detection of Small Lesions in Medical X-Ray Image Based on Multi-Scale Fractal Feature

D ) was applied in this paper. The MF D values of different regions in a medical image are normally different. According to the values of the MF D , small lesions in a medical x-ray image can be detected. This method has been applied to a digital bone fracture x-ray image. Experimental result showed that the MF D values of the background regions are between 0.005 and 0.020; the MF D values of the normal regions are between 0.040 and 0.070; and the MF D values of the
