Realization of Image Denoising Based on Four-order Partial Differential Equations

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.
