BUILT-IN MATHEMATICA SYMBOL

MorphologicalComponents

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.

Details and Options Details and Options

MorphologicalComponents assigns sequential integers to different connected components.
MorphologicalComponents gives 0 for pixels that correspond to the background in the image.
MorphologicalComponents[image] is equivalent to MorphologicalComponents[image, 0].
MorphologicalComponents by default treats all eight pixels surrounding a given pixel as adjacent.
The option setting CornerNeighbors->False treats only the four pixels in the coordinate directions as adjacent.
MorphologicalComponents works with binary, grayscale, and other images.
MorphologicalComponents takes a Padding option. The default setting is Padding->0, corresponding to a black background.
MorphologicalComponents supports a Method option that specifies the connectivity of elements. Possible settings include:

	"Connected"	labels connected components (default)
	"Nested"	labels nested connected components
	"Convex"	labels objects within non-overlapping convex regions
	"ConvexHull"	finds non-overlapping convex hulls
	"BoundingBox"	finds non-overlapping bounding boxes
	"BoundingDisk"	finds non-overlapping bounding disks
