Benchmarking : Smil vs scikit-image

Morphological Image Libraries

nestor - Summary of SpeedUp results (by image size)

These page presents SpeedUp results for the nestor computer.

We can see here results for each function, and for each image in the original size 256x256 and size 8192x8192. For results in intermediate sizes, see the detail results : binary and gray images.

Numbers in red color means Smil is faster than Scikit-Image.
