2013-05-27 02:06:06 -0500 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

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 !

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);
image.setImageBitmap(bmp);
