Micro-crack Detecting method based on improved anisotropic diffusion model using extended kernel

摘要

anisotropic diffusion models based on the micro-crack inspection method according to the invention , the cross direction of the primary tilt using the expanded gradient applied to second-class room diffusion model, the diffusion image obtained by deriving the diffusion coefficient of a higher value as compared to the basic slope and expansion inclination , excellently detecting the micro-cracks in the small number of iterations compared to the conventional algorithm, you may not only can be detected with a thickness similar to the thickness of the actual micro-cracks . ;
