研制了一种基于运动目标检测技术的交互式图片浏览系统．首先使用高斯混合模型对背景进行建模，提出把传统的 RGB 颜色空间转化为 YCbCr 颜色空间的改进方法，以提高检测算法对光照变化的鲁棒性，实现对前景移动目标的有效检测，进而分离出目标对象，同时结合肤色检测技术和Canny 边缘检测算法来实现对移动目标的定位．最后对实际开发的系统进行功能测试验证，取得了良好的预期效果．

Proposed in this paper is an interactive photo- browsing system based on the moving target detection.In this system,the Gaussian mixture model is used to construct a background model and the traditional RGB color space is converted into YCbCr color space to improve the robustness of the system to illumination varia-tion.Thus,the moving foreground target is effectively detected and the target object is further separated.More-over,in order to locate a moving object,the skin segmentation technology is combined with the Canny edge de-tection algorithm.The developed system is finally tested by experiments,with satisfactory results being ob-tained.
