摘　　要：针对VB数值计算能力和图像处理能力不足,以及不利于系统开发的缺点,介绍基于VB和MatrixVB并利用四阶偏微分方程实现图像去噪的方法。利用VB作为主要编程语言,借助MatrixVB矩阵运算函数库建立了处理系统,实现了图像去噪功能。该方法将Matlab的强大计算功能与VB的Windows用户界面开发方面的优势结合起来,缩短了软件的开发周期。软件测试结果表明,计算方法正确,方法稳定可靠,算法设计优化,所开发的应用软件具有界面友好,计算速度快,系统资源消耗少,操作简便易行,能满足图像滤波的要求。According to the situation that Visual Basic is insufficient in numerical computation and image processing abili- ty, and is weak in system development, the realization of four -order partial differential equations for image denoising by incorporating Visual Basic and MatrixVB is introduced. Using program language Visual Basic as main language for image denoising, combining with MatrixVB matrix calculating function. The incorporated advances of Matlab＇s powerful calculation function and Visual Basic＇s friendly graphic user interface shorten the period of software development. It has been demonstrated by the in- stance that the calculating procedure is accurate, steady and credible. The software interface is friendly and the function is perfect. Beside this,resource expenditure of computer is low and calculating speed is quick,the software is easy to learn and convenient to use. It is a good tool for image denoising.
