P-harmonic model of image inpainting algorithm based on curvature driven

在p-harmonic模型的基础上,引入曲率诱导项,提出一种新的图像修复模型,建立了与之对应的扩散方程,利用有限差分法对所建立的扩散方程进行数值求解,给出该修补模型的离散格式和具体的算法步骤,得到修复的图像。实验结果表明:该算法能提高修复的速度,并且具有较好的修补效果。

A new image inpainting algorithm based on p-harmonic model is proposed in this paper by introducing the curva- ture driven term, corresponding diffusion equation is established, finite difference method is adopted for the established dif- fusion equation, and the discrete format of the inpainting model and the algorithm of specific steps is given to obtain the in- painted image. Experiment results show that the proposed algorithm can improve the inpainting speed and has better inpaint- ing results.
