Abstract:

In this paper, we take the pixel values of an image as temperature of some plane objects. By applying the theories of partial differential equations and image zooming, we design two new models for image processing based on isotropic and anisotropic diffusion. We also give algorithmic schemes for experiments. Finally we compare these two new models with other models. Our experimental results show that the proposed models work well on image zooming and provide better quality of zoomed images.
