Fast and accurate scale estimation method for object tracking

Many of the existing tracking methods do not estimate the object scale (width, height), only the location (x, y). In this paper we present a method which can accurately estimate the object scale given the location. The proposed approach works by cascading two methods together; such that each method refines the estimate by removing the false scale samples. Our method does not depend on the tracking technique and can be applied with any tracking system. We apply our approach to an existing tracker and compare the performance on benchmark sequences. The proposed method outperforms the existing tracker, while hardly affecting the speed.
