基于分数阶偏微分方程的图像放大模型
Image zooming model based on fractional-order partial differential equation
摘要
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 character‐istics 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 .关键词
