MorphologicalComponents[image] gives an array in which each pixel of image is replaced by an integer index representing the connected foreground image component in which the pixel lies. MorphologicalComponents[image, t] treats values above t as foreground. MorphologicalComponents[video, ...] computes connected components in frames of video.

Find the connected components in a binary image: In[1]:=MorphologicalComponents[]// Colorize Out[1]=
