Abstract In radiography imaging, contrast, sharpness and noise there are three fundamental factors that
determine the image quality. Removing noise while preserving and sharpening image contours is a
complicated task particularly for images with low contrast like radiography. This paper proposes a new
anisotropic diffusion method for radiography image enhancement. The proposed method is based on
the integration of geometric parameters derived from the local pixel intensity distribution in a nonlinear
diffusion formulation that can concurrently perform the smoothing and the sharpening operations.
The main novelty of the proposed anisotropic diffusion model is the ability to combine in one process
