Proposal for the handling of B&W images

[lcipolina]

Hello!
Thank you for this fantastic model.

I am using it with Black and White images (i.e. gray) which only have 2 channels.
Your code reads images using matplot lib, which will only read the 2 channels of an BnW image.

It will be better to read images using openCV, which adds the extra channel.

So replacing everything that reads the image like this:

img = plt.imread(fname)[:,:,:3] #this won't work in BnW

by using:

img = cv2.imread(fname) #this adds the extra channel and converts to np array on the fly

I can make the changes in your code and crete a pull request if you want.

Cheers, Lucia.

Hi! Could you please point to the places we use plt.imread? I do no see any in our main code
