Results of automatic initialization experiments using settings ASM* and ASM*_B

	Participant
	S1	S2	S3	S4	S5	S6	S7	S8
ASM* good initialization	73	75	75	73	75	75	66†	28†
ASM* average error, mm	0.71	0.37	0.29	0.35	0.29	0.34	0.68	1.92†
ASM*B good initialization	74	75	75	73	75	75	75	34†
ASM*B average error, mm	0.63	0.30	0.28	0.30	0.28	0.30	0.27	2.01†

Good initialization shows the total number of images (out of 75) that were fitted with <1 mm average error and average error (in mm) across all 75 frames is also reported. ASM, active shape model; ASM*, ASM extensions for skeletal muscle; ASM*_B, automatic initialization.

^†Cases where poor initialization was common.
