Application of PDE-Based Image Smoothing Method in Digital Image Processing
Lijuan Han, Cheng Yuan-hang, Zhao Yi-wei, Ren Ping-hong · 2009
Compared with traditional image smoothing method, partial differential equations -based image smoothing method is better in preserving image features while suppressing image noise. The PDE-based image denoising smoothing algorithm and an improved algorithm based on it are discussed in the paper. A good result is achieved in the experiment of identifying flaws on precise optical components’ surface with the application of the methods.
