摘要

骨骼信息以人体骨关节为基础，特征清晰简单，不易受外观因素影响。本文提出了一种改进的Gist特征ExGist来描述人体骨关节的骨骼信息，用于人体动作识别。利用OpenPose和热力学图提取关节坐标，利用ExGist进行特征提取。ExGist的优点是在保持Gist特征原有优势的同时，能够有效地表征骨架信息的局部和全局特征。与Gist相比，ExGist在不同分类器上取得了更好的结果。此外，与C3D和APTNet相比，我们的模型也获得了更好的结果，准确率为89.2%。

Human action recognition based on skeleton features

Based on human bone joints, skeleton information has clear and simple features and is not easily affected by appearance factors. In this paper, an improved feature of Gist, ExGist, is proposed to describe the skeleton information of human bone joints for human action recognition. The joint coordinates are extracted by using OpenPose and the thermodynamic diagram, and ExGist is used for feature extraction. The advantage of ExGist is that it can effectively characterize the local and global features of skeleton information while maintaining the original advantages of Gist feature. Compared with Gist, ExGist achieves better results on different classifiers. Additionally, compared with C3D and APTNet, our model also obtains better results with an accuracy rate of 89.2%.
