BUILT-IN MATHEMATICA SYMBOL

DistanceTransform

DistanceTransform[image]
gives the distance transform of image, in which the value of each pixel is replaced by its distance to the nearest background pixel.

DistanceTransform[image, t]
treats values above t as foreground.

Details and Options Details and Options

DistanceTransform gives an Image object in which the value of each pixel is the absolute Euclidean distance in pixels to the nearest pixel of background.
ImageAdjust[result] normalizes the pixel values in the result from DistanceTransform.
For multichannel images, DistanceTransform operates on the intensity averaged over all channels.
DistanceTransform[image] is equivalent to DistanceTransform[image, 0].
The following option can be given:
DistanceFunction EuclideanDistance distance metric function
The default setting is DistanceFunction->EuclideanDistance. Other typical settings include ManhattanDistance and ChessboardDistance.
DistanceTransform takes a Padding option. The default setting is Padding->1.
