[NEW] The DukeMTMC dataset is taken down due to privacy concerns... Will reopen when it's clear.

[NEW] Benchmark evalution code-base is released! Please refer to this repo for more details.

DukeMTMC4ReID

DukeMTMC4ReID dataset is new large-scale real-world person re-id dataset based on DukeMTMC. We use a fast state-of-the-art person detector for accurate detections. After verified by the ground truth, for each identity, we uniformly sample 5 "good" bounding boxes in each available camera, while retaining all the "FP" bounding boxes in the corresponding frames. To summarize, the relevant statistics of the proposed DukeMTMC4ReID dataset are provided below:

• Images corresponding to 1,852 people existing across all the 8 cameras
• 1,413 unique identities with 22,515 bounding boxes that appear in more than one camera (valid identities)
• 439 distractor identities with 2,195 bounding boxes that appear in only one camera, in addition to 21,551 ?FP? bounding boxes from the person detector
• The size of the bounding box varies from 72×34 pixels to 415×188 pixels
