Abstract: | Tracking of moving objects in real-time scenes is a challenging research problem in computer vision. This is due to incessant live changes in the object features, background, occlusions, and illumination deviations occurring at different instances in the scene. With the objective of tracking visual objects in intricate videos, this paper presents a new color-independent tracking approach, the contributions of which are threefold. First, the illumination level of the sequences is maintained constant using fast discrete curvelet transform. Fisher information metric is calculated based on a cumulative score by comparing the template patches with a reference template at different timeframes. This metric is used for quantifying distances between the consecutive frame histogram distributions. Then, a novel iterative algorithm called conditionally adaptive multiple template update is proposed to regulate the object templates for handling dynamic occlusions effectively. The proposed method is evaluated on a set of extensive challenging benchmark datasets. Experimental results in terms of Center Location Error (CLE), Tracking Success Score (TSS), and Occlusion Success Score (OSS) show that the proposed method competes well with other relevant state-of-the-art tracking methods. |
