MARS dataset
What is MARS Dataset?
The MARS (Motion Analysis and Re-distinguishing proof Set) is a large video-based individual reidentification dataset. MARS is an extension of the Market-1501 dataset. The dataset was created by placing six near-synchronized cameras (one of which was a 640*480 SD camera, and the other five cameras were 1,080*1920 HD cameras) on the campus of Tsinghua University. The MARS dataset is made up of 1,261 unique pedestrians that were captured by two or more cameras.

MARS Dataset FAQs
What is the MARS dataset for Python?
MARS (Motion Analysis and Re-identification Set) is a large-scale video-based person reidentification dataset that is a follow-up to the Market-1501 dataset. In addition, the dataset includes 3,248 distractors to make it more realistic. The tracklets were generated automatically using the Deformable Part Model and the GMMCP tracker (mostly 25-50 frames long).
How to download the MARS dataset in Python?
You can load MARS dataset fast with one line of code using the open-source package Activeloop Hub in Python. See detailed instructions on how to load MARS dataset training subset and testing subset in Python.
How can I use MARS dataset in PyTorch or TensorFlow?
You can stream MARS while training a model in PyTorch or TensorFlow with one line of code using the open-source package Activeloop Hub in Python. See detailed instructions on how to train a model on the MARS dataset with PyTorch in Python or train a model on the MARS dataset with TensorFlow in Python.
