Aiming at the problems of poor cross-view adaptability and insufficient model training stability existing in current gait recognition technologies, a dual-channel spatiotemporal convolutional generative adversarial network (GAN) model that incorporates style encoding was proposed. The model employs a dual-channel spatiotemporal convolutional network to extract complex spatiotemporal and gait features from gait images, while a style encoder is introduced to minimize the semantic discrepancies between the generated images and the original ones, thereby enhancing the stability of the generator. Experimental results on the CASIA-B dataset demonstrate that, compared to GaitGAN, the proposed model achieves recognition rate improvements of 23%, 28%, and 22% at three representative gait angles of 54°, 90°, and 126°, respectively. Additionally, the method shows strong applicability on the OU-MVLP large-scale cross-view gait database, achieving an average recognition accuracy of 89.1%, significantly improving cross-view gait recognition performance.
OU-MVLP(Multi-view large population dataset)[14]是目前全球规模最大的步态识别跨视角数据集,包含10 307个样本,覆盖14个视角(0°,15°,…,270°),每个视角下均包含两个步态序列(#00和#01),且步行状态保持一致。数据集按照官方设定分为训练集和测试集,分别包括5 153名样本和5 154名样本。在训练和测试环节中,序列#01和#00均用作训练集和测试集,为跨视角步态识别的性能评估提供了规范化的实验基准。
