HOW FALL DETECTION WORKS

01Every person gets an ID and a tracked box — legs do not need to be visible
02A standing baseline (torso direction, hip height, stature, floor) is locked per person
03A fall probability p is computed every frame; above the threshold the person is FALLING
04Held down for the hold time → FALLEN, FALL ALERT and alarm. Getting up → RECOVERING → STANDING

Experimental software, not a certified medical or emergency device. Keep the tab in the foreground and the camera steady; monitoring pauses when the tab is hidden.
