Otsu method #6

Closed drmatthews closed 5 years ago

drmatthews commented 5 years ago

The Otsu method is used for automatic thresholding of low resolution slide image. This works well when thresholding the image using skimage.threshold_otsu. This builds the image histogram and then runs applies the Otsu method. When this is done on just the histogram data stored in the slide metadata it doesn't work quite as well.

Had removed high grey level bins from histogram.
