Hi,
On my recent batch of mocap videos, some moves seems to be tricky for iPi. My actor walks and then turns back, but not completely. So his legs are slightly rotated and then he makes gestures with his arms.
One of my cams isn't perfectly placed, so there is some visual occlusion and sometimes iPi inverts the two legs. A few manual tweaks and everything's fixed.
But on "non-problematic" (I mean, not occluded) segments of the session, Ipi has a hard time figuring the correct orientation of the feet. They're correctly tracked and placed "position-wise", but their orientation do not match. See :
It looks more like Ipi tries to guess it, by comparing it with previous frames and the orientation of the torso. Maybe that's how it works ?
Also, black shoes are recommended in the iPi doc. But really, once recorded with webcams, black shoes and jeans seem almost the same color. As I had a middle-grey floor when shooting, wouldn't it be better to have, say white shoes in this case ?
