结合注意力和纹理特征增强的行人再识别

针对现有行人再识别算法在处理图像分辨率低、光照差异、姿态和视角多样等情况时,准确率低的问题,提出了基于空间注意力和纹理特征增强的多任务行人再识别算法.算法设计的空间注意力模块更注重与行人属性相关的潜在图像区域,融入属性识别网络,实现属性特征的挖掘;提出的行人再识别网络的纹理特征增强模块通过融合不同空间级别所对应的全局和...

Attention and Texture Feature Enhancement for Person Re-identification

In view of the low accuracy of existing person re-identification to deal with low image resolution,illuminative difference,posture and perspective diversity,this paper proposes a multi-task pedestrian recognition algorithm based on spatial attention and texture feature enhancement.The spatial attention module designed by the algorithm pays more attention to the potential image areas related to the pedestrian attributes,which further explores attribute features.The texture feature enhancement module of the person re-identification network reduces the interference of light,occlusion on person re-identification by fusing the global and local features corresponding to different spatial levels.Finally,the multi-stage weighted loss function integrates the attribute features and pedestrian features to avoid the decrease of mean average precision caused by attribute heterogeneity.Experimental results show that the mean average precision can achieve 81.1%and 70.1%respectively on the Market-1501 and DukeMTMC-reID datasets.
