【摘要】 "信号与系统"课程中的输入和输出信号在时域都是一维电信号,不够直观;数字图像处理的输入和输出信号都是二维图像,非常直观。为了更好地帮助学生理解课程中信号处理的原理和效果,本文将数字图像处理若干工程案例引入"信号与系统"课程的讲解。课堂教学效果表明,数字图像处理工程案例的引入对"信号与系统"课程教学具有良好的辅助作用。更多还原

【Abstract】 The input and output signals in time domain involved in the Signals and Systems course are one dimensional electric signals which are certainly counterintuitive. While the input and output signals of digital image processing systems are two-dimensional images,which are very intuitive. In order to help the students understanding the theories of signal processing and demonstrating the abstract theory,this paper employs several typical project cases of digital image processing into the Signals and Systems course. The classroom application proves the effectiveness of this approach,which plays a good supporting role to the traditional teaching and learning of the Signals and Systems course.更多还原
