提出了一种改进直方图映射和均值移位结合的目标跟踪算法,根据目标模型各成分直方图比例系数建立索引表,索引号为颜色值,索引内容为颜色对应的归一化目标模型直方图,在索引表中查询输入图像颜色值构建反映目标出现概率灰度图;均值移位算法在生成灰度图中快速定位目标位置。对比实验结果表明,改进的直方图映射算法从根本上抑止模型背景干扰,均值移位算法准确定位目标;系统能实时准确跟踪运动目标。-An improved histogram mapping and integration of the mean shif

介绍了红外成像波门形心跟踪算法的原理,通过建立跟踪误差模型,讨论分析了红外成
像波门形心跟殊算法的误差,当误判概率越小,波门内目标像素越多,背景像素越少时,形心跟踪误差越小 当信噪比越大,相关搜索的次数越少,相关运算的像素总数越多时,正确匹配系数越高。试验证明,该算法不仅能减小跟踪误差,而且能提高跟踪的精确度和稳定性。

:基于背景建模的运动目标分割是智能视频监控的重要任务,模型的质量直接影响到检测、跟踪、识别等运动分析的准确性.当前的建模方法多是单层的,忽略了像素特征在时域和空域上的联系,模型描述不够准确,对于背景扰动、全局光照变化及复杂的室内外场景等多种情况鲁棒性不强,导致了分割中出现空洞和噪声点.针对这些问题提出了一种双层建模的方法,在第一层提取时域上的像素亮度特征采用码本建模,第二层提取邻域纹理特征采用基于中心对称的局部二值模式建模.实验证明该方法在用于运动分割时,比常用方法具有更好的准确性和鲁棒性.-M

针对摄像机固定下的复杂背景环境,对采集到的视频图像的图像数据用混合高斯背景建模方法实现前景/背景分割,实现运动目标检测和跟踪。在进行前景检测前,先对背景进行训练,对图像中每个背景采用一个混合高斯模型进行模拟,每个背景的混合高斯的个数可以自适应。然后在测试阶段,对新来的像素进行GMM匹配,如果该像素值能够匹配其中一个高斯,则认为是背景,否则认为是前景。由于整个过程GMM模型在不断更新学习中,所以对动态背景有一定的鲁棒性。最后通过对一个有树枝摇摆的动态背景进行前景检测,取得了较好的效果。-For c
