摘　　要：数字图像处理课程涉及较多的数学推导,理论难度大。为降低学生学习难度,提高学生学习兴趣,在成果导向教育(Outcome-Based Education,OBE)理念指导下,将项目案例引入教学过程中。文章以图像零水印项目为例,对零水印的生成过程和检测过程进行介绍,并进行了案例分析。通过项目式训练,以提高学生综合运用所学知识的能力,同时增强学生对版权保护方面的认知。The course of digital image processing involves a lot of mathematical derivations and has high theoretical difficulty.To reduce students’learning difficulty and enhance their interest in learning,project cases are introduced into the teaching process under the guidance of the outcome-based education philosophy.This article takes the image zero watermark project as an example to introduce the generation and detection process of zero watermarks,and conducts case analysis.Through project-based training,students’ability to apply their knowledge comprehensively is enhanced,and at the same time,their awareness of copyright protection is strengthened.
