import numpy import vigra.noise import vigra.arraytypes image = vigra.arraytypes.ScalarImage(numpy.random.rand(100,100)*255, dtype=numpy.float32) vigra.noise.noiseVarianceClustering(image)
I have applied upstream patch[0] that makes this code a bit less fatal:RuntimeError: Invariant violation!
noiseVarianceListMedianCut(): internal error (k: 0, k1: 0, k2: -1, noise.size(): 0, clusters.size(): 1). I have also disabled the test that was causing build failures. [0] http://www.informatik.uni-hamburg.de/~meine/hg/vigra/rev/70df92a12ef2 -- Jakub Wilk
