Segmentation and Merging effects

	AUC	Segment Count	Over-segmentation Ratio
In BACOM	0.9256	845	0.965
CBS	0.9373	1171	1.34
PCF	0.9279	4906	5.60
DBS	0.9452	967	1.104

Here the entire test dataset consists of 104 test sequences and a total of 876 test segments. The AUC correspond to the ROC curves in Fig. 4(d). Segment count is the number of segments generated by the four algorithms. Over-segmentation ratio is a ratio of the segment count generated by each algorithm and the actual number of test segments
