Digital image processing is an important course, which has strong theoretical and practical needs for students. This paper proposes a digital image processing education platform (DIPEP) based on C# and .NET framework. It has the image processing, analyzing and visualization function. Students can develop and integrate algorithms into the platform quickly and easily. Moreover, algorithm flow application and algorithm management can be applied by students in DIPEP based on workflow technology. Tested by experiments, DIPEP meets the requirement of interface flexibility, information sharing, algorithms safety and efficiency.
