Medical X-ray image enhancement method based on dark channel prior

Abstract

Medical X-ray image is used as the important information and basis for the clinical diagnosis, while its quality digressed because of the interferences caused by the human body structure, equipments, and environmental factors. This paper verifies that the X-ray image degradation caused by the X-ray scattering which is similar as the haze scattering. Dark channel prior is widely used on haze removing, we applied the dark channel prior method in medical X-ray image enhancement. The experimental results show that the method can effectively increase the image contrast, highlight the details.
