摘要
为改善教学质量,提出基于高校思政课实践教学学习系统的微视频功能设计研究。分析前期需求,开发设置情境、内容展示、师生互动与总结评论四个模式,利用摄像机完成微视频制作;在后期处理中使用抗线性共谋攻击的视频水印算法,经过子区域选取、JND值计算与水印嵌入等步骤实现微视频功能设计。仿真实验表明方法能够帮助激发学生学习兴趣,提高思政课实践教学效果。
In order to improve the teaching quality,this paper puts forward micro video function design of the practical teaching system of Ideological and political course in colleges and universities.The preliminary requirements are analyzed,the video watermarking algorithm against linear collusion attack is used to realize the micro video function design through sub region selection,JND value calculation and watermark embedding.Simulation experiments show that the method can stimulate students' interest in learning and improve the learning effect.
