数字图像处理研究性实验教学的改革与实践——基于分数阶偏微分的图像边缘检测

Reform and practice of research-style experimental teaching by digital image processing:Image edge detection based on fractional-order partial differential

以开放实验"图像边缘检测创新方法设计实验"为例,介绍了数学实验室如何在传统实验中适当引入新的研究内容开展创新性实验。用分数阶微分方法研究图像边缘检测,对数字图像处理研究性实验教学进行探索,使图像处理实验成为培养学生创新能力的载体。实践表明,教学效果明显改善,该创新实验的引入不仅能有效地加深学生对数字图像处理基本理论的理解,而且能培养学生的实践动手能力,有效地实现创新能力的渗透式培养。

Taking the opening experiment ＂image edge detection method of innovation design experiment＂ as an example, this paper presents the mathematical laboratory in traditional experiments to introduce new research content of carrying out innovative experiments. The fractional differential method is used to research image edge detection, and explore digital image processing to research experiment teaching, which makes image processing experiments become the carrier of cultivating students ~ innovative ability. Practice shows that the teaching effect is improved obviously, the innovative experiment, not only can effectively enhance students understanding of the basic theory of digital image processing, but also can cultivate students＇ practical ability, innovation ability effectively to achieve penetration-type training.
