摘要
视频图像处理与分析在视频侦查中有广泛的应用,选取运动目标跟踪和图像检索作为示例进行实验设计说明。实验中采用LK算法实现运动目标跟踪,验证基于特征点跟踪方法的有效性,加深学生对运动目标跟踪的理解,激发了学生进一步研究的兴趣。采用基于MATLAB的图像检索辅助软件,实现基于颜色特征和纹理特征的图像检索,明确不同方法的特点及适用场合,不仅巩固了理论知识,又提升了学生的实践创新能力。
Video image processing and analysis in video detection has a wide range of applications, so,this paper selects the moving target tracking and image retrieval as an example of experimental de-sign. Experiments using LK algorithm to achieve the goal of tracking, verify the effectiveness of the method based on the feature point tracking,to enhance the understanding of students to track the tar-get, to stimulate the interest of students for further research. Image retrieval based on color feature and texture feature is realized using the image retrieval assistant software based on MATLAB,to clarify the characteristics and application of different methods, which not only solidifies the theoretical knowl-edge ,but also enhances the students’ practical and innovative ability.
