摘 要: 不同摄像设备之间存在角度、分辨率等差异,同时行人兼具刚性和柔性的特性且外观易受穿着、姿态、遮挡物和视角等因素的影响。基于此,文章从生成对抗网络与姿态特征等方面对行人重识别问题展开深入研究,提出了一种姿态可交换行人重识别框架(PSG-Net)。该框架将样本中的每个行人编码为姿态代码,视觉代码,通过切换姿态代码,生成高质量的姿态合成图像。在Market-1501、DukeMTMC-reID和CUHK03数据集上的实验结果表明,该方法实现了识别性能改进,并在Market-1501数据集上的排序第一(rank-1),结果能达到95.1%,优于大多数先进的方法。 |

Abstract: There are differences in angle and resolution between different camera devices, and pedestrians have both rigid and flexible characteristics, and their appearance is easily affected by wearing, posture, obstruction, and perspective. Based on this, this paper conducts in-depth research on pedestrian recognition from the aspects of Generative adversarial network and attitude characteristics, and proposes a gesture exchangeable pedestrian recognition framework (PSG-Net). This framework encodes each pedestrian in the sample as pose code and visual code, generate high-quality pose synthesis images by switching pose codes. The experimental results on Market-1501, DukeMTMC reID, and CUHK03 datasets show that the proposed method has achieved recognition performance improvement, with ranking first (rank-1) results reaching 95.1% on Market-1501 dataset, which is superior to most advanced methods. |
