Replace dilate to closing or opening #6

Hi!

I noticed that the edged image has edges bigger than the original document boundary. It happens because of dilation. It would be better to replace it to closing or opening. On my tests closing works a bit greater score. cv2.morphologyEx(gray, cv2.MORPH_CLOSE, kernel)

Ivan I'm having a hard time finding the PHP library. Or in javascript are there missing files?

@Momarthe1 This rep uses OpenCV on Python. I'm not an expert in web libraries, so I can't recommend any.
