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 shift tracking algorithm, according to the target model histogram of the ratio coefficient of each component index tables, index number for the color value, index the content for the color corresponding to the normalized histogram of target model , in the index table query input image color value for establishing the probability of targets grayscale　mean shift algorithm to generate grayscale quickly locate the target location. Comparison of experimental results show that the improved histogram mapping algorithm fundamentally suppress background interference model, the mean shift algorithm for accurate targeting　system is able to accurately track moving objects.
