Person Re-identification Method Based on Color Attack and Joint Defence. (arXiv:2111.09571v4 [cs.CV] UPDATED)

The main challenges of ReID is the intra-class variations caused by color
deviation under different camera conditions. Simultaneously, we find that most
of the existing adversarial metric attacks are realized by interfering with the
color characteristics of the sample. Based on this observation, we first
propose a local transformation attack (LTA) based on color variation. It uses
more obvious color variation to randomly disturb the color of the retrieved
image, rather than adding random noise. Experiments show that the performance …
