Hi Stefan, So I think SWT is patented, isn't it? That looks fantastic--algorithms such as these are exactly what I had in

mind.

I wonder if implementation of this paper is considered to be a GSoC project, I would like to work on it. *Another question* : What is the status of SIMD optimization in scikit-image? Does Cython support such kind of optimization works? Is there any SIMD optimized functions available in scikit-image? Regards Abid K
