A simple Open Frameworks application using the MS Kinect depth sensing camera via libfreenect and ofxKinect.
The computer searches for my manboobs and draws a bra or pasties on top. Music is played when titties are detected.
I'm using OpenCV on the depth image. I look for a person-sized blob and use it's centroid to approximate a search box wherein to detect 2 boobs. The bra or pasties are drawn using the centroids of these boob blobs. A third blob detector is used to look for the hand to change between bras.
The second half of the video shows a projection mapping of the bras/pasties onto my chest. This is all running in realtime and in low light conditions with a bad background. Yes, the Kinect sensor is pretty awesome!
