Abstract

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 componentspsila surface with the application of the methods.
