为解决行人重识别的训练数据集中自动检测出的行人图像背景过大和行人部分缺失的错位现象问题,使用空间变换网络层对图像错位进行处理。为优化整个网络的深度学习过程,提高图像检索能力,增加网络特征层,使用奇异值向量分解方法对其进行处理。将行人对齐网络和奇异向量分解相结合,构造奇异值分解行人对齐网络,既可解决图像错位问题,又提高图像特征的相似性度量的效果。在Market1501、CUHK03和DukeMTMC-reID数据集上进行试验,并与行人对齐网络和其他深度学习与非深度学习的行人重识别方法进行比较,试验结果中整个网络的平均检索精度和行人图像第一次匹配正确的概率平均达到了65%和80%左右,这表明奇异值分解行人对齐网络可以提高对行人匹配的效果。

In order to solve the problem that the background of pedestrian image was too large and the part of pedestrian was missing in the training data set of pedestrian recognition,the spatial transformation network layer was used to process the image dislocation.In order to optimize the deep learning process of the whole network and improve the image retrieval ability,a feature layer was added to the network,and singular value vector decomposition was used to process it.By combining the pedestrian alignment network with the singular vector decomposition and constructing the singular value decomposition pedestrian alignment network,the image dislocation problem could be solved and the effect of similarity measurement of image features could be improved.Experiments were conducted on Market1501,CUHK03 and DukeMTMC-reID datasets,and compared with pedestrian alignment network and other pedestrian re-recognition methods of deep learning and non-deep learning.In the experimental results,the values of rank-1 and mAP mean average precision reached 80%and 65%on average,which indicated that singular value decomposition of pedestrian alignment network had certain benefits on pedestrian matching effect.
