METHORD AND APPARATUS FOR REAL-TIME OBJECT TRACKING USING COLOR HISTOGRAMS

摘要

A real-time object tracking method and an apparatus thereof using a color histogram capable of continuously tracing the change of an object which is chosen on a track station are provided to modify a reference histogram based on the present histogram of the window which is chosen on the track station. A histogram generator(30) produces a plurality of windows from a successively inputted image. A similarity calculator(40) produces the similarity with the set standards histogram by each present histogram. A tracking target selector(60) extracts a standards histogram and the most high present histogram among the current histograms. The window corresponding to the extracted present histogram is selected as a tracking window. A modifier(70) modifies the standard histogram by reflecting the standard histogram.
