Maybe the simplest one should be to have texton (patches 9x9) with a PCA behind then the clustering. That would be the one without skimage dependences.

Not sure how to extract features without skimage, unless we use some sparse coding for that. And that would probably take a long time. I guess the most simple datasets for this would be cifar 10 and caltech 101. And it would probably not run fast enough for a plot example. ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
