Matlab環境中的基礎模糊演算法教程, 包含基本模糊理論和工具箱的使用(A basic tutorial for using fuzzy toolbox in Matlab, containing fuzzy theory.)

We introduce a new approach to tone management for photographs. Whereas traditional tone-mapping operators target a neutral and faithful rendition of the input image, we explore pictorial looks by controlling visual qualities such as the tonal balance and the amount of detail. Our method is based on a two-scale non-linear decomposition of an image.
