|A method and apparatus for analyzing a sequence of images.
Signal-to-noise ratios are identified for potential tracks using a tree
having hierarchies of nodes identifying potential positions for an object
over a period of time and using the sequence of images. Each hierarchy in
the hierarchies of nodes represents a time and the potential positions in
the tree form the potential tracks for the object. A potential track is
selected from the potential tracks as an established track for the object
using the signal-to-noise ratios, and a detection of the object is
