The space nonlocal derivative operator to introduce the curvature driven diffusion equation, image restoration based on model-driven proliferation of non-local curvature. The main difference with the original model is that the original model to be repaired using space of local information to estimate the missing pixels pixels, the new model takes advantage of all the pixels and a pixel to be repaired similar to estimate missing pixel, full use of the global information image. Numerical experiments show that the new model in image restoration, especially in terms of texture image restoration is very effective.
