MorphologicalBinarize

MorphologicalBinarize
creates a binary image from image by replacing all values above the upper threshold with , also including pixels with intensities above the lower threshold that are connected to the foreground.
MorphologicalBinarize
uses t as the upper threshold, automatically choosing a suitable value for the lower threshold.
MorphologicalBinarize[image]
chooses the lower and the upper threshold automatically.
  • MorphologicalBinarize effectively performs hysteresis thresholding and is typically used as part of edge-detection methods.
  • MorphologicalBinarize works with any image. It converts multichannel and color images into grayscale images, then produces an image in which every pixel has value or .
  • The option setting CornerNeighbors->False treats only the four pixels in the coordinate directions as adjacent.
