| 2013-05-27 02:06:06 -0600 | commented question | How to recognize hand on android devices Convert the source image to the HSV color space, and then use the Core.inRange function to capture a specific color, I set the skin color range from (0,30,20,0) to (40,255,255,0), (I'm not sure whether it is appropriate) the final effect is not ideal, too. Maybe need to do some more complex processing |

| 2013-01-04 02:46:27 -0600 | commented answer | How to recognize hand on android devices I used convexHull and convexityDefects function to find hand convex hull and the convexity defects of it in these day,but i didn't know what should to do for distinguish them yet? By the way,if i want to read the number that the gesture showed,how to realize? I searched in the internet much ,but nothing helpful. Can you help me ? I am a fresher, really appreciate ! |

| 2012-12-27 20:59:10 -0600 | commented answer | How to recognize hand on android devices Thank you,rics! I already recognized the skin,then i have to distinguish hand from face.Do you have good advice? |
| 2012-12-27 02:42:22 -0600 | commented answer | How to recognize hand on android devices I write the follow code according to handDetection.cpp,but the result is negative .What's wrong?By the way do you know which functions in opencv-android library can replace the "cvAnd" and "cvOr" functions? the code : Scalar hsv_min = new Scalar(0,30,80,0);
Scalar hsv_max = new Scalar(0,30,80,0);
Imgproc.cvtColor(src, hsv_image, Imgproc.COLOR_BGR2HSV);
Core.inRange(hsv_image, hsv_min, hsv_max, hsv_mask);
Utils.matToBitmap(hsv_mask, bmp); |
