2013-12-05 23:06:01 -0500 asked a question How can we select Just a part of a binary image?

I'm working on hand gestures using Skin tone recognition. Now, since the face also falls in the HSV range of skin tone the face part also comes as positive in the binary image on which i'm applying the convexhull and convexity defects method to detect the palm. I just wanted to know if it was possible to detect the face and remove it from the binary image.

It's showing an error "Parameters cannot be written, because file hand.xml/params.xml cannot be opened" where hand.xml is my "data".

can you elaborate on how to use train_cascade and LBP features. Is there any tutorials available. Thanks

I'm trying to train a haar cascade of positive images 1749 and negative images 3867. My positive vector file contains 885 samples. I'm trying to detect palm. Is this the correct ratio of number positive and negative images? And what should be the value of the parameters of my haar cascade?

i am trying to train a haar cascade using opencv_traincascade.exe with 101 positive samples n the vector file and 50 negative images. what should be my command so that i can avoid the above mentioned problem.

i am using windows 8, 64-bit system.
