Abstract

Existing datasets for person re-identification do not consider the situation where person encounter occlusion and already have bad lighting conditions, in order to solve this problem, this paper conducts an in-depth research on data augmentation methods for person re-identification and proposes a novel data augmentation method that integrates random erasing and local grayscale transformation. Random erasing generates training images with different degree of occlusion, while local grayscale transformation generates training images with deviations caused by lighting changes. Combining the two can effectively reduce the risk of overfitting and improve the generalization ability of the model, and the experimental results show that rank-1 and mAP improve 1.1% and 1.3% compared to the model using only random erasing, and 1.7% and 2.9% compared to the model without data augmentation. Thus the fusion of random erasing and local grayscale transformation is an effective new data augmentation method.
