Visual tracking is an area of computer vision with many practical applications, and thus it is one of the field's subdisciplines with the biggest potential impact. There are good reasons to track a wide variety of objects, including airplanes, missiles, vehicles, people, animals, and microorganisms. While tracking single objects alone in images has received considerable attention, tracking multiple objects simultaneously is both more useful and more problematic. It is more useful because objects we want to track often exist in close proximity to other similar objects. It is more problematic because the objects of interest can touch, occlude, and interact with each other; they can enter and leave the image; and we must be able to tell them apart. In addition, multiple object tracking must still deal with all the hard problems of single object tracking, including running at a reasonable rate and adapting to changing background conditions.

This workshop is intended to highlight the problems and solutions that distinguish computer-vision-based multi-object tracking from single-object tracking. We want to identify new approaches to these issues from both inside and outside the computer vision community.
