Tracking a Conductor’s Baton

A system to track an uninstrumented conductor’s baton by computer vision techniques is developed. An initial seek mode locates a baton in an image frame without prior knowledge; a subsequent track mode uses temporal information to cope with motion blur and noise. The seek mode utilises the characteristic form of detected edges to guide a maximal intensity trace. The track mode enhances this technique by dovetailing with optical flow to give robust tracking, even with considerable motion blur and poor quality images.
