Title: Testing K-curvature + Convex Hull Hand Tracking
Added: Dec 11, 2011
Author: tcboy88
Duration: 0:44
Description:
For left picturebox algo:1) use convex hull find the corner points2) calculate these points k-curvature angle3) if lower than certain value, assume it is finger4) start from the finger point, expand to left and right, find middle of the 2 points, then plot it blue color (u can see blue color line, it is for getting finger direction, stil under progress) For right picture box algo (smaller)1) find convex hull and convexity defects2) if the depth point of convexity defect is lower than start/end point + if the start point of convexity defect is higher than middle point of whole contour = assume it is finger (this algo dont work well if hand is not vertical upright)3) find middle point of palm, draw line from middle point to finger point (red line) this finger direction is not as good as the previous 1

Jan 13, 2012 - very nice project. I am also doing work for hand gesture recognition using convex hull and convexity defects. Would you be able to send me your source code?? Much Thanks. My email is zner11@gmail.com
