# FindThreshold

 FindThreshold[image] finds a global threshold value that partitions the intensity values in image into two intervals.
• FindThreshold works with any image. It converts multichannel and color images into grayscale images, and then finds a global threshold.
• FindThreshold also works with real arrays of arbitrary dimensions.
• Possible settings for the Method option include:
 {"BlackFraction",b} make a fraction b of all pixels black "Cluster" cluster variance maximization (Otsu's algorithm) "Entropy" histogram entropy minimization (Kapur's method) "Mean" use the mean level as the threshold "Median" use the median pixel level as the threshold "MinimumError" Kittler-Illingworth minimum error thresholding method
• The default setting is Method.
