You should also share the section of code where you are making the function call. From the error it could be that you are calling the function with a zero sized image. Check if you are actually accessing the webcam image, e.g. by saving it in a file. – Antonio

This was mainly because of opencv files that i have installed. 32 bit and 64 bit is a tricky one!
