HAARCASCADE HAND .XML DOWNLOAD FREE

I found this list of steps to do but I have the slightest idea where to start and what exactly to prepare and do. Unfortunately no matter what haarcascade I used, and what modifications I made to the detectMultiScale function I could not get a reliable read of hands due to many false positives. Sign up using Email and Password. This took me exactly 5 seconds by just opening google and search for "haar classifier training opencv". Lets say in the given image the hand is not present then I will take any contour and consider it as the hand. Stack Overflow works best with JavaScript enabled. My first attempt to implement hand tracking was to use a HAAR Cascade classifier trained to recognize hands.

Creating the description file of positive samples 2. I decided to attempt this method after seeing how quickly Haar Cascades could be used to track faces within a camera frame.

So I started thinking can I use the haar cascade to determine the rectangle of the hand and focus on that area, but I tried searching online for the xml but I think it is not available like face detection. Sign up using Email and Password. I guess I relied too much on this forum that I didn't even try searching using Google.

Converting the trained cascade into a xml file 6. Active 2 years, 9 months ago. In the end I decided to move back to my original algorithm. Is haartraining a good approach? Stack Overflow works best with JavaScript enabled.

If you would like to experiment with the convex based hand tracking check out the cv2 branch in the git repo. People will gladly help out then. Fairly quickly I found that the expression of this algorithm was fairly limited, and that if I wanted to really emulate the experience of playing a theremin I would need to implement a computer vision algorithm that would give me exact coordinates as opposed to average brightness.
