A deep person re-identification model with multi visual-semantic information embedding

Abstract

The local features of different body parts have been widely used to learn more discriminative representation for person re-identification, which act as either extra visual semantic information or auxiliary means to deal with the issue of misalignment and background bias. However, the existing person re-identification works mainly focuses on the common impact of multiple body parts while failing to explicitly explore the influence of body edge contour. As the edge contour is one of the most significant visual-semantic clues for object detection and person identification in the blurred scene, this paper intentionally explores the effect of edge contour clues on person re-identification and proposes a deep learning framework with multi visual-semantic information embedding, including body parts and edge contour. Meanwhile, we conceive a practical strategy which can effectively fuse the different body part features and reduce the dimensionality of features. Extensive experimental results on four benchmark data sets show that our model has achieved competitive accuracy compared to the state-of-the-art models.
