为改善视频监控中人流量检测的准确性问题,提出一种利用头发颜色特征的人流量跟踪检测方法。该方法对输入图像同时做如下两个操作:基于头发颜色特征的二值化和基于混合高斯模型的前景提取。对这两者合并后的结果做特征判别就可以得到人头区域。以人头区域为目标进行跟踪,分析运动轨迹特征后可以判断行人的进出方向及数目。实验表明该方法在双向行走、行人密集及背景干扰条件下均有很高的正确率。并且,每帧图像平均处理时间只需20 ms,完全可以满足实时处理的要求。
為改善視頻鑑控中人流量檢測的準確性問題,提齣一種利用頭髮顏色特徵的人流量跟蹤檢測方法。該方法對輸入圖像同時做如下兩箇操作:基于頭髮顏色特徵的二值化和基于混閤高斯模型的前景提取。對這兩者閤併後的結果做特徵判彆就可以得到人頭區域。以人頭區域為目標進行跟蹤,分析運動軌跡特徵後可以判斷行人的進齣方嚮及數目。實驗錶明該方法在雙嚮行走、行人密集及揹景榦擾條件下均有很高的正確率。併且,每幀圖像平均處理時間隻需20 ms,完全可以滿足實時處理的要求。

In order to improve the accuracy of the people counting detection in video surveillance,a people tracking and detection method based on hair color feature is proposed in this paper. The input images are processed with the following two operations at the same time:binarization based on hair color feature and foreground extraction based on Gaussian mixture model. Through analyzing the merging results of the two operations,head regions can be got. By tracking head regions and trajectory analysis,the moving direction and number of visitors will easily come to the judgment. The experimental result shows that the method has the high-accuracy even in the conditions of bidirectional moving,dense crowd or background interference. Further-more,the average processing time for per frame is only 20 ms. It can fully meet the requirements of real-time processing.
