Method for image noise removal based on PDEs
Liu Chen-hua, Bing Sheng Yan · 2006
In order to improve the effect of image noise removal,it is very important to use apropriate difference format in discreting partial differential equation.The higher precision of difference format,the stronger stability.A type of difference format of concealed alternation was adopted to discrete partial differential equation,which was compared with result of general show format after discretizaion.The experimental results indicate that by using difference format of concealed alternation to discrete partial differential equation,not only high precision can be received,but also the effect of image noise removal is distinct.It is an effective tool to use difference format of concealed alternation to discrete partial differential equation for image noise removal.
