diffusion filter

基本解释

These filters may boil down to solving nonlinear diffusion equations with initial values being input images.
這些非線性圖像濾波大多源於求解初始值爲輸入圖像的非線性擴散方程。
In this paper, an enhancement algorithm for noised document image based on anisotropic diffusion and shock filters is presented.
基於沖激濾波模型的圖像增強算法能夠銳化圖像邊緣。
Stained quartz glass for filters has been made by ion diffusion under high-tension electric field. The equipment and process are described.
利用高壓電場離子擴散法試制濾光石英玻璃，介紹了該法的裝置與工藝。
