Abstract
A space is modeled using images from a set of cameras in the space. An easy to use tool is provided that allows users to identify a reference location in an image and a corresponding reference location on a floor plan of the space. Based on these correspondences, a model is generated that can map a point in a camera's view to a point on the floor plan, or vice-versa. Subjects moving through the space are identified and tracked using the model and attributes associated with a subject. In a specific implementation, the attributes include velocity, color, size, and position. In a specific implementation, the space is a retail store and the subjects are customers browsing through the retail store.
