MorphologicalEulerNumber

MorphologicalEulerNumber[image]
computes the morphological Euler number of regions in a binary image.

treats values above t as foreground.

MorphologicalEulerNumber[image] by default gives the total number of connected white regions in image, minus the number of black holes that occur inside those regions.

MorphologicalEulerNumber 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.

MorphologicalEulerNumber takes a Padding option. The default setting is Padding, corresponding to a black background.

Count the number of white objects minus the number of holes:

Count the number of bright spots, specifying an explicit thresholding value:

Count the number of white objects minus the number of holes:

By default, all eight neighbors around a given pixel are treated as being neighbors:

Treat only the four non-corner pixels as neighbors:
