Scale-adaptive object tracking using color centroids

Abstract

We propose a stable scale-adaptive tracking method that uses the centroids of the target colors in the target localization and scale adaptation. Because of the spatial information inherent in the centroids, a direct relationship can be established between the centroids and the scale of the target region. After the zooming factors are calculated, the unreliable zooming factors are filtered out to produce a reliable zooming factor that determines the new scale of the target.
