A summary of the age, body mass index (BMI), weight, height and left and right mid upper arm circumference (MUAC) of the 31 study participants (11 female, 20 male).

Illustration of photo capture setup: Views 1 to 5 –relative orientations between the camera and the participant’s left and right arm.
Fig 2.
Manually annotated markers of a photo from A) view 1, and B) view 3, of participant 0007. Black circles are the corners of the reference object; black solid line is the floor line; blue cross is the top of the head; red dashed line is the bounding box; green x’s are the two edges of the left mid-upper arm; and yellow x’s are the two edges of the right mid-upper arm. Note that the floor line and the bottom edge of the bounding box do not align.
