QUESTION
I have a python image processing function, that uses tries to get the dominant color of an image. I make use of a function I found here https://github.com/tarikd/python-kmeans-dominant-colors/blob/master/utils.py
It works, but unfortunately I don't quite understand what it does and I learned that np.histogram
is rather slow and I should use cv2.calcHist
since it's 40x faster according to this: https://docs.opencv.org/trunk/d1/db7/tutorial_py_histogram_begins.html

, or better, which values I have to input.

and np.bincount
to get the most dominant color could be suggested. Also, in the linked page, it talks about bincount
as a faster alternative, so that could be the way to go.
