Abstract
While numerous algorithms
have been proposed for object tracking with demonstrated success, it remains a
challenging problem for a tracker to handle large change in scale, motion,
shape deformation with occlusion. One of the main reasons is the lack of
effective image representation to account for appearance variation.
Most trackers use
high-level appearance structure or low-level cues for representing and matching
target objects. In this paper, we propose a tracking method from the
perspective of mid-level vision with structural information captured in
superpixels.
We present a
discriminative appearance model based on superpixels, thereby facilitating a
tracker to distinguish the target and the background with mid-level cues. The
tracking task is then formulated by computing a target-background confidence
map, and obtaining the best candidate by maximum a posterior estimate.
Experimental results
demonstrate that our tracker is able to handle heavy occlusion and recover from
drifts. In conjunction with online update, the proposed algorithm is shown to
perform favorably against existing methods for object tracking.
