TABLE IV.
Segmentation performance — sequences not successfully segmented automatically. For each sequence, the first row gives automatic-method results (labeled “auto”). The second row presents results using the semi-automatic key-frame-based method; numbers in the “Key Frame” column denote the frame(s) Il interactively selected as a key frame(s) for restarting the segmentation method. The last four rows give aggregate results over the 5 sequences.
