Hi Dr. Kang,

Are we to implement the functions used from scratch? To what extent may we utilize the OpenCV libraries?

Thanks

what about Otsu’s method? Because first we need to create a greyScale image, then get a histogram and only after that we can implement Otsu's method, but if we using opencv Mat for histogram, than how I can work with Mat type to implement Otsu's method? I think it need array type to implement Otsu's. So I found convertTo method but it works in java I can't find same one for python.
