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.

Download MARS Dataset in Python

Instead of downloading the MARS dataset in Python, you can effortlessly load it in Python via our Deep Lake open-source with just one line of code.

Load MARS Dataset Training Subset in Python

				
					import deeplake
ds = deeplake.load("hub://activeloop/emnist-mars-train")

Load MARS Dataset Test Subset in Python

				
					import deeplake
ds = deeplake.load("hub://activeloop/emnist-mars-test")

How to use MARS Dataset with PyTorch and TensorFlow in Python

Train a model on MARS dataset with PyTorch in Python

Let’s use Deep Lake built-in PyTorch one-line dataloader to connect the data to the compute:

				
					dataloader = ds.pytorch(num_workers=0, batch_size=4, shuffle=False)

Train a model on the MARS dataset with TensorFlow in Python

				
					dataloader = ds.tensorflow()

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 the MARS dataset fast with one line of code using the open-source package Activeloop Deep Lake in Python. See detailed instructions on how to load the MARS dataset training subset and testing subset in Python.

How can I use the MARS dataset in PyTorch or TensorFlow?

You can stream the MARS dataset while training a model in PyTorch or TensorFlow with one line of code using the open-source package Activeloop Deep Lake in Python. See detailed instructions on how to train a model on the Mars dataset with PyTorch or train a model on the MARS dataset with TensorFlow.
