In this model the processed image can be obtained on the asymptotic states of its solution. The diffusion tensor is chosen to change dynamically in such a way as to process the image without affecting its interesting features. The proposed anisotropic diffusion can be classed as a nonstandard Volterra equation. Experimental results are shown on test and medical images, which illustrate the ability of our model to detect fine objects in a noisy image
