    摘要:

    针对现有持续人体动作识别算法实时性不高的问题,本文提出了一种基于DTW积分直方图的动态捕捉方法。首先,利用积分直方图对原始动作进行分类;然后,聚类各种时空姿态建立动作的统计表示,并采用巴氏距离测量两个直方图的相似性;最后,根据动态时间规整方法设计了动态程序识别算法。通过大型数据集的测试以及与几种最新方法的比较证明了本文方法的高效性,即使在数据库包含噪声和相似动作的情况下,本文方法仍然取得了很好的识别效果。

    Abstract:

    To solve the problem of Real-time differential in current ongoing human action recognition algorithm, data motion capture method based on DTW integral-histogram is proposed. Firstly, the original action is classified by integral-histogram. Then, spatio-temporal series of poses are clustered to create a statistical representation of actions and the similarity between two histograms is measured using Bhattacharyya distance. Finally, a dynamic programming algorithm, inspired from the Dynamic Time Warping method is proposed to finish recognition. The approach proposed is tested on well-known benchmark datasets and compared to several state-of-the-art methods. The obtained results have clearly shown the success and effectiveness of our solution, even in the presence of noise and/or similar actions in the datasets.
