Hello,
In the context of my previous email to pythonvision
https://groups.google.com/d/topic/pythonvision/SSCF4LUlRKQ/discussion
I made a timing comparison between mahotas & scikits-image.
operation | mahotas | pymorph | skimage ------------+----------+----------+--------- erode | 10.80 | 14.33 | 80.17 dilate | 11.44 | 8.93 | 41.59 open | 22.45 | 23.20 | 80.18 center mass | 7.05 | NA | NA sobel | 75.03 | NA | 105.72 cwatershed | 201.03 | 56586.50 | 290.41 daubechies | 19.05 | NA | NA haralick | 306.48 | NA | 7391.37
(Best viewed with fixed-width fonts)
The unit of measurement is the time it takes to run ``numpy.max(image)`` Mahotas is always faster than skimage (although pymorph is better for certain morphological basic operations). I used GCLM in skimage to stand for Haralick, which is a rough approximation.
I attach the script that generates these (against github skimage). If you think that I have used skimage incorrectly, please let me know.
Best,
