摘要
为了解决数字图像处理课程教学中传统方法的不足,探讨了基于空域处理的图像增强理论探究式教学法的实施.以直接灰度变换方法的教学内容为例,将教学过程分为课前准备、课堂教学和课后拓展3个阶段,以课堂教学作为主要阶段进行教学设计,并划分为理论学习、案例教学、项目训练和研究归纳4个主要环节.教学实践证明,该方法遵循教学活动的一般规律,让学生理解图像增强的关键所在,有助于帮助学生深入理解空域处理理论.在教学过程中创设的学术研究的教学情景,提高了课堂教学效率,为学时少的专业课程的教学开拓了思路.
In order to solve the shortcomings of the traditional methods during teaching digital image processing course,the implementation of the inquiry teaching method is discussed based on the spatial domain processing theory of image enhancement.Taking the direct gray scale transformation as an example,the teaching process is divided into three stages,such as the preparation before the class,the classroom teaching and the expansion after the class.The classroom teaching is used as the main stage for teaching design,it is divided into the four main steps,such as the theoretical study,the case teaching,the project training and the research induction.The teaching practice has proved that the method follows the general rules of teaching activities,it makes the students understand the key to image enhancement,helps the students to deeply understand the theory of spatial processing.The teaching situation of the academic research created in the course of teaching improves the efficiency of the classroom teaching,it also has opened up a thinking for teaching the professional courses of less class.
