Attributes for Re-identification

We present here our attributes ground-truth labels, as used in the below publications. Attributes are a compelling representation for re-identification; they're low-dimensional, often easy to classify, and lastly they are quite compatible with other standard tools such as distance-metric learning and transfer.
