Abstract (EN)
We propose a new model for zooming digital images. This model, driven by a partial differential equation, performs a balance between a linear zoom on homogenous zones and an anisotropic diffusion based. zoom near edges. This allows the advantages of linear zoom models and of some nonlinear ones to be combined while leaving out their drawbacks.
