kinect

Let me explain my need before I explain the problem. I am looking forward for a hand controlled application. Navigation using palm and clicks using grab/fist. Currently, I am working with Openni, which sounds promising and has few examples which turned out to be useful in my case, as it had inbuild hand tracker in samples. which serves my purpose for time being. What I want to ask is, 1) what would be the best approach to have a fist/grab detector ? I trained and used Adaboost fist classifiers on extracted RGB data, which was pretty good, but, it has too many false detections to move forward.

So I have convert the getDisplayPosition from the beta version of the Kinect SDK to the full version. Here's what I have right now The Original private Point getDisplayPosition(Joint joint) { float depthX, depthY; nui.SkeletonEngine.SkeletonToDepthImage(joint.Position, out depthX, out depthY); depthX = Math.Max(0, Math.Min(depthX * 320, 320)); //convert to 320, 240 space depthY = Math.Max(0, Math.Min(depthY * 240, 240)); //convert to 320, 240 space int colorX, colorY; ImageViewArea iv = new ImageViewArea(); // only ImageResolution.Resolution640x480 is supported at this point nui.NuiCamera

I'm trying to crop a rectangular region of a video RGB. First i found the coordinates of head joint and with this coordinates i drew a rectangle over the RGB video. Now i want to show in another video just the image that is inside of the rentangle in the first image. Any help would be great. video RGB is displayed in a "RGBvideo" Image Control. cropped image i want to display in a "faceImage" Image Control I've search online but couldn't find a solution to it. I am confuse. thank you so much Welcome to Stack Overflow, please don't ask the same question multiple times. With less popular tags

I need to develop an application where a user (physiotherapist) will perform a movement in front of the Kinect, I'll write the data movement in the database and then the patient will try to imitate this motion. The system will calculate the similarity between the movement recorded and executed. My first idea is, during recording (each 5 second, by example), to store the position (x, y, z) of the points and then compare them in the execution time(by patient). I know that this approach is too simple, because I imagine that in people of different sizes the skeleton is recognized differently, so
