[Numpy-discussion] Counting the Colors of RGB-Image

2012-01-15 Thread apo 

Counting the Colors of RGB-Image, 
nameit im0 with im0.shape = 2500,3500,3
with this code:

tab0 = zeros( (256,256,256) , dtype=int)
tt = im0.view()
tt.shape = -1,3
for r,g,b in tt:
 tab0[r,g,b] += 1

Question:

Is there a faster way in numpy to get this result?


MfG elodw
