    <p>I'm trying to determine <strong>skeleton joints</strong> (or at the very least to be able to track a single palm) using a <strong>regular webcam</strong>. I've looked all over the web and can't seem to find a way to do so.</p> <p>Every example I've found is using Kinect. I want to use a single webcam.</p> <p>There's no need for me to calculate the depth of the joints - I just need to be able to recognize their X, Y position in the frame. Which is why I'm using a webcam, not a Kinect.</p> <p>So far I've looked at:</p> <ul> <li>OpenCV (the "skeleton" functionality in it is a process of simplifying graphical models, but it's not a detection and/or skeletonization of a human body).</li> <li>OpenNI (with NiTE) - the only way to get the joints is to use the Kinect device, so this doesn't work with a webcam.</li> </ul> <p>I'm looking for a C/C++ library (but at this point would look at any other language), preferably open source (but, again, will consider any license) that can do the following:</p> <ul> <li>Given an image (a frame from a webcam) calculate the X, Y positions of the visible joints</li> <li>[Optional] Given a video capture stream call back into my code with events for joints' positions</li> <li>Doesn't have to be super accurate, but would prefer it to be very fast (sub-0.1 sec processing time per frame)</li> </ul> <p>Would really appreciate it if someone can help me out with this. I've been stuck on this for a few days now with no clear path to proceed.</p> <p><strong>UPDATE</strong></p> <p>2 years later a solution was found: <a href="http://dlib.net/imaging.html#shape_predictor" rel="noreferrer">http://dlib.net/imaging.html#shape_predictor</a></p>

    1. COThis is really difficult with a single webcam, even more so in real time. Hence the Kinect. To only track a single palm you should be able to modify this real time tracker to do the job: http://www4.comp.polyu.edu.hk/~cslzhang/CT/CT.htm. IT works really well and their C++ code uses OpenCV.

    3. COIt would help if you would give a little bit more context, so we have an idea why it should absolutely not involve Kinect (and maybe suggest a viable alternative within the bounds of this context)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
