A Novel Image Restoration Algorithm Using Neural Network Based on Variational PDE Model
WU Ya, Zhang Hongying · 2006
The variational partial differential equation (PDE) model is introduced into image restoration framework using neural network. A novel image restoration algorithm based on harmonic diffusion equation is given. And, the convergence of this restored algorithm is also analyzed. The proposed algorithm could deblur the degraded image while preserve edges. Experimental results show that the presented algorithm is superior to the traditional restoration algorithm in preserving image edges, and has a better restoration effect
