报告摘要：

In this talk, we introduce an adaptive enhancement model with selective smoothing for restoration of degraded document images with

 blur, noise and bleed-through, which involves an adaptive shock filter and a selective diffusion process. A novel numerical scheme is 

developed for solving this model by combining explicit finite difference and exponential smoothing. Numerical experiments show that

 the model is very effective for restoration of degraded document images with blur, noise and bleed-through, and has averagely the 

best performance on the DIBCO (Document Image Binarization Competition) series datasets, compared to five PDE (partial differential 

equation)-based models for restoration of degraded document images. Besides, the proposed model can also be applied to restoration 

of other real-world images.
