python wrapper for basic c implementation of kmeans
pip install kmeans
import kmeans means = kmeans.kmeans(points, k)
points should be a list of tuples of the form (data, weight) where data is a list with length 3.
For example, finding two mean colors for a group of pixels:
pixels = [ [(15, 20, 25), 1], # [(r,g,b), count] [(17, 31, 92), 5], # ... Lots more ... ] mean_pixels = kmeans.kmeans(pixels, 2)
In this case, the weights passed in may be the frequency of the pixels occuring in an image, or some preference to pull the means towards a color.
I wanted to apply the implementation there to images much larger than 200x200. Running a 4k x 3k image was approaching 60 seconds on a nice computer, so I decided to rewrite the kmeans implementation in c.
