We have been contructing a video dataset of detected people walking through the atrium of a building, where the data comes from an overhead camera.
Because of the data volume, we are not recording the video images, but are doing target detection on the images and save the detection records.
The records include a bounding box and a colour histogram for each detected target. Because of lighting, camera jitter and stationary objects, there are detections of non-people, too. After detection, we also have applied our person tracker, recording the trajectories as both lists of detections and splines.
By July 19, 2010, there were 29 million target detections, of which an estimated 8.3 million were real targets, resulting in 96K observed trajectories. And we're still acquiring data!
You might find it interesting to use the data. It's at:

The data was acquired in the Informatics Forum, the main building of the School of Informatics at the University of Edinburgh.
By the way, there are over 120 public image and video datasets on CVonline at:
