Presents a new angiogram image enhancement algorithm. The X-ray angiogram image quality is often not good due to various kinds of reasons, which cause a lot of difficulties to vessel segmentation or vessel axis extraction. To overcome this shortcoming, we firstly analyze the original anisotropic diffusion. Then the characteristics of angiogram images are investigated, and a new model of contrast is presented. Based on this contrast model, we propose a new anisotropic diffusion to enhance the X-ray angiogram images, which can adaptively choose the conductance parameter. Experimental results show that this new method is very effective.
