Thick8 Posted May 27, 2013 Posted May 27, 2013 (edited) I've been using Facetrack with a 3 point hat clip. It works great except during the day when I have some IR interference from a window with open blinds. Closing the blinds is NOT an option (just ask my wife). I tried a visible light camera with the faceAPI but due to the fact I am facing a corner with my setup, the camera can't distinguish my facial features unless the exposure rate is at about 10 FPS (unacceptable). Can I use the faceAPI with an infrared camera? Can I use it both in daylight and semi darkness? Any help would be appreciated. Thanks.

rabidmanatee Posted May 27, 2013 Posted May 27, 2013 Using the same setup with a window behind as well. What worked for me is remove the IR filter from this Logitech 910 and 2 swatches of floppy disk as a visible light filter in front of the camera. My pointtracker settings are Threshold: middle of line, Max Dia 15, Min Dia 1. Works day or night. Your settings my vary.
Thick8 Posted May 27, 2013 Author Posted May 27, 2013 I think I only installed 1 layer of floppy disk in my camera. I was kind of hoping I could loose the hat and sensor array. I bought 2 Microsoft VX-800 cameras. I think I'll take them back and get a nightvision camera just to try it out.

rabidmanatee Posted May 27, 2013 Posted May 27, 2013 Oh I see, read it as you were using trackclip pro active LED, which is what I have. Since you're using the reflective clip, you're much more sensitive to ambient IR. Just guessing but if you bathed yourself in more IR or enlarged the size of the clip reflectors. The easiest thing might be just put a partition behind your chair to block out the light.
Thick8 Posted May 28, 2013 Author Posted May 28, 2013 I have a 3 IR led active "cap" type clip. Unfortunately putting up a portion is not possible. What I'm thinking is to 1. loose the active IR led system. 2. Use faceAPI as the tracker source. 3. use a night-vision type USB camera. I'm wondering if the IR light from the camera's emitter will "light up" my face enough for the FaceAPI to distinguish my features even with a significant amount of IR background noise. Or will the back-light wash out my features to the camera. Will a "bright" IR source shining on my face for long periods be harmful?
