Three Ways to Improve the Performance of Real-Life Camera-Based Fall Detection Systems

Table 2

Results of robust background subtraction (BGS) trained on and trained using visible falls of but validated using . Results from [28] using slightly different data set added as reference.

Method	SENS	PPV	TP	FN	FP
Robust BGS (using tracker and detector) for	45.5%	1.4%	10	12	688
Robust BGS only trained on visible falls for	40.9%	1.6%	9	13	526
Original BGS using APM [28] for	23.8%	2.2%	5	16	225
Original BGS using APM [28] for	38.1%	0.58%	8	13	1360
