摘要:

这项工作的目标是根据人们走路的方式(即步态)在视频中进行识别。虽然经典方法通常从二进制轮廓序列中获得步态特征,但在这项工作中,我们探索使用卷积神经网络(CNN)从低级运动特征(即光流分量)学习高级描述符。我们对具有挑战性的TUM-GAID数据集上提出的CNN架构进行了彻底的实验评估。实验结果表明,使用光流的时空长方体作为CNN的输入数据允许获得步态任务的最新结果,其图像分辨率比先前报告的结果低八倍(即80 × 60像素)。

英文摘要:

This work targets people identification in video based on the way they walk (i.e. gait). While classical methods typically derive gait signatures from sequences of binary silhouettes, in this work we explore the use of convolutional neural networks (CNN) for learning high-level descriptors from low-level motion features (i.e. optical flow components). We carry out a thorough experimental evaluation of the proposed CNN architecture on the challenging TUM-GAID dataset. The experimental results indicate that using spatio-temporal cuboids of optical flow as input data for CNN allows to obtain state-of-the-art results on the gait task with an image resolution eight times lower than the previously reported results (i.e. 80x60 pixels).
