Video Image Tracking Technique Based On Shape-BasedMatching Algorithm

摘要

We present an application of digital video imagesrnfor object tracking. In order to track a fixed object, which wasrnshoot on a moving vehicle, this study develops a shape-basedrnmatching algorithm to implement the tracking task. Becausernthe shape-based matching algorithm has scale and rotationrninvariant characteristics, therefore it can be used to calculaternthe similarity between two variant shapes. An experiment isrnperformed to track the ship object in the open sea. The resultrnshows that the proposed method can track the object in thernvideo images even the shape change largely.
