| 摘 要： | 在视频监控领域聚众等异常事件检测有着广泛的应用前景,然而相关研究在国内发展还比较缓慢。在这里给出了基于隐马尔科夫模型的聚众事件的检测方法,其简单过程如下:首先在高斯混合模型检测出目标的基础上,针对聚众事件视频序列的特性,完成了关于帧图像二元组的特征提取;然后,在合理选择初始模型的前提下使用Baum-Welch算法训练聚众事件的隐马尔科夫模型;最后通过实拍的视频序列验证其有效性。

| Abstract: | In the field of video surveillance,the crowd and other abnormal events detection have a broad application prospects,however,the development of related research in China is still relatively slow. The abnormal event detection method based on the Hidden Markov Model are given here,a simple process just as follows:First,for the characteristics of crowd events video sequences,the dual feature vector extraction was completed on the basis of the Gaussian Mixture Model to detect the target; Then,Hidden Markov Model... |
