| 摘 要： | 提出了一种基于堆叠深度卷积沙漏网络的步态识别方法。为了解决人体建模中关节点准确定位的问题,采用基于深度卷积的沙漏网络来提取步态图上的关节点坐标,并计算肘关节与膝关节的角度作为运动特征。为了解决行走速度变化带来的影响,采用动态时间规整(Dynamic Time Warping)对特征序列进行距离计算。通过最近邻分类器对结果进行准确分类。该方法在公共CASIA-B数据集与TUM-GAID数据集上进行了验证并与其他方法进行比较,结果表明该方法有较高的识别率。

| Abstract: | A new approach for gait recognition is proposed based on stacked depth convolution hourglass network. In order to locate the joints in human modeling accurately, the convolution hourglass network based on deep convolution network is used to extract the joint coordinates of gait image, and the angle between elbow joint and knee joint is calculated as motion characteristics. Considering the influence of the change of walking speed, the dynamic time warping algorithm is used to calculate the distance of the feature sequence. Finally, the nearest neighbor classifier is used to classify the results accurately. Experimental results show the effectiveness of the proposed method in comparison with other state-of-the-art methods on the public databases CASIA-B and TUM-GAID for gait recognition. |
