Content The dataset is about tracking objects in 2D in movies with fixed and moving cameras. Most of the objects are pedestrians but there are a few other examples I just downloaded the zip and am now looking at what is actually inside. A kernel will hopefully clarify how the ground truth can be read. Acknowledgements The dataset was originally download from the MOT challenge site at https://motchallenge.net/data/2D_MOT_2015/#download Inspiration Your data will be in front of the world's largest data science community. What questions do you want to see answered?
