Abstract: An anisotropic diffusion method and apparatus based on the direction of an edge are disclosed. In the anisotropic diffusion apparatus, directional pattern masking is performed to determine the direction of an edge in an image including noise, and values obtained through the directional pattern masking are convoluted to calculate the magnitude of an image. If the calculated magnitude value of the edge is larger than a threshold value, the edge of the image is preserved, while if the calculated magnitude value of the edge is not larger than the threshold value, noise cancellation is strengthened, whereby noise can be effectively canceled (or concealed) while preserving the edge representing the characteristics of the image, and thus, an image of high quality can be obtained.
