An online feature evaluation method for visual
object tracking is put forward in this paper. Firstly, a
combined feature set is built using color histogram (HC)
bins and gradient orientation histogram (HOG) bins
considering the color and contour representation of an
object respectively. Then a novel method is proposed to
evaluate the features’ weights in a tracking process
using Kalman Filter, which is used to comprise the
inter-frame predication and single-frame measurement
of features’ discriminative power. In this way, we
extend the traditional filter framework from modeling
motion states to modeling feature evaluation.
Experiments show this method can greatly improve the
tracking stabilization when objects go across complex
backgrounds.
