Image Restoration Model of PDE Variation
Mingjun Wang, Shuxian Deng · 2009
This paper study a PDE variational model to image denoising and restoration. The existence and uniqueness of the solution is discussed. A new model of image denoising and restoration is deduced by gradient descent flow method. Then, A new numerical analysis model is obtained. The model can preserve the edge feature and smooth the image. The numerical experiments show that the model delivers better results in image denoising and restoration.
