| 摘 要： | 为了提高图像去噪的效果,在对偏微分方程进行离散时使用恰当的差分格式是非常重要的,差分格式的精度越高稳定性越强越好。采用交替方向隐式的差分格式对偏微方程进行离散,并与用一般的显示格式进行离散后的结果进行比较,实验结果表明,使用交替方向隐式的差分格式对偏微方程进行离散,不仅能得到较高精度同时去噪效果明显,使用交替方向隐式的差分格式对偏微分方程进行离散是图像去噪的一种有效的工具.

| Abstract: | 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. |
