Synopsis

HxImageRep HxDistanceTransform (HxImageRep img)

Return value

HxImageRep

The distance transform of the input image.

Description

The function HxDistanceTransform calculates the shortest distance (approximately) to the background for every object pixel, through a recursive morphological operation. Background pixels are defined as pixels with value 0, while object pixels are defined as pixels with value 1. The input image should be a 2D scalar image of the type short, byte or integer. The image should also contain at least one background pixel. The resulting image is a scalar double 2D image.

Remarks

Valid image types

This function only accepts 2D scalar image, with short, byte or integer types, containing solely pixel with value 0 or value 1. The input image should at least contain one pixel with value 0.
