Hi everybody. To restart a conversation we had before on SIFT: Do we want patented algorithms in sklearn? I just found out that alpha-expansion and alpha-beta swaps are patented, which makes me very unhappy. What do patents mean: We can implement patented algorithms and distribute them under BSD license. If someone uses the software for commercial purposes, they can be sued by the patent holder. If we choose to include patented algorithms, we can include them with a warning. Then there is no problem in having SIFT or including graph cuts with alpha expansion. Cheers, Andy
