Abstract：A new image zooming model based on the fractional-order partial differential equation is proposed, which adopts the idea of total variation. Simulation results show that the new model is capable of preserving the characteristics of image edge, and it can retain more texture details than the integer order partial differential equation model. The model is therefore effective and practical for image zooming.
