A partial differential equation approach to image zoom

We propose a new model for zooming digital image. This model, driven by a partial differential equation, will balance between linear zooming on homogenous zones to anisotropic diffusion near edges. This allows to combines advantages on linear zoom models and of some non linear ones while leaving out their drawbacks.
