摘要
图像检索技术在公安工作中发挥着重要作用,但其理论知识比较抽象,学生仅通过理论知识的学习很难深入理解该技术。为了辅助学生对图像检索技术的理解与掌握,基于OpenCV和Qt设计并开发了一个包含图像预处理、图像特征提取和图像检索3个模块的图像检索教学软件,涵盖了实现图像检索所需的每一步操作,并能够以图像或数值的形式可视化图像检索的中间处理结果。
The image retrieval technology plays an important role in the public security work,but it's so abstract that it's hard to understand deeply only through theoretical knowledge for the students.In order to help students understand and master the image retrieval techniques,an image retrieval technology teaching aids software was designed and developed in this paper.The software includes image preprocessing,image feature extraction and image retrieval modules,covering every step of the operation needed to realize the image retrieval.It also displays the intermediate processing results of image retrieval in the form of images or numbers.
