Accurate feature point tracks through long sequences are a valuable substrate for many computer vision applications, e.g. non-rigid body tracking, video segmentation, video matching, and even object recognition. Existing algorithms may be arranged along an axis indicating how global the motion model used to constrain tracks is. Local methods, such as the KLT tracker, depend on local models of feature appearance, and are easily distracted by occlusions, repeated structure, and image noise. This… CONTINUE READING
