论文摘要
步态识别的关键目标是从步态序列中获取框架间的步行习惯代表。但是，与框架内特征相比，框架之间的关系尚未得到足够的关注。在本文中，提出了以光流为动机，提出了双边运动为导向的特征，这可以使经典的卷积结构具有直接在功能级别上直接描绘步态运动模式的能力。基于此类特征，我们开发了一组多尺度的时间表示，迫使运动上下文在各种时间分辨率层面上得到丰富的描述。此外，设计了一个校正块，以消除轮廓的分割噪声，以获取更精确的步态信息。随后，将时间特征集和空间特征组合在一起，以全面地表征步态过程。在CASIA-B和OU-MVLP数据集上进行了广泛的实验，结果实现了出色的识别性能，这证明了该方法的有效性。
The critical goal of gait recognition is to acquire the inter-frame walking habit representation from the gait sequences. The relations between frames, however, have not received adequate attention in comparison to the intra-frame features. In this paper, motivated by optical flow, the bilateral motion-oriented features are proposed, which can allow the classic convolutional structure to have the capability to directly portray gait movement patterns at the feature level. Based on such features, we develop a set of multi-scale temporal representations that force the motion context to be richly described at various levels of temporal resolution. Furthermore, a correction block is devised to eliminate the segmentation noise of silhouettes for getting more precise gait information. Subsequently, the temporal feature set and the spatial features are combined to comprehensively characterize gait processes. Extensive experiments are conducted on CASIA-B and OU-MVLP datasets, and the results achieve an outstanding identification performance, which has demonstrated the effectiveness of the proposed approach.
