Hi,

I pass a 3D integer matrix to the label function in scikit.measure

My original matrix contains integers in the range {-1..4}. But he output matrix from label function contains label from {1..199}. I am expecting it to be between {-1 .. 4}. Why so ? --

Hi Shameem, scikit.measure.label labels the connected components in your data (from the documentation): """ *Two pixels are connected when they are neighbors and have the same value.* """ If you look at the first example in the documentation: http://scikit-image.org/docs/dev/api/skimage.measure.html#skimage.measure.la... you'll notice that the input array contains integers in the range {0..1} but the output labels are in the range {0...4}. Otherwise what would you expect from the label function? Kind Regards, Kevin
