Find triple points

Parameters:

Return type:

Image instance

Return a binary image where pixels are True if the corresponding pixel in the binary image is a triple point, that is where three single-pixel wide line intersect. These are the Voronoi points in an image skeleton.

Example:

>>> from machinevisiontoolbox import Image
>>> img = Image.String('000000|011110|001000|001000|000000')
>>> img.print()
   0 0 0 0 0 0
   0 1 1 1 1 0
   0 0 1 0 0 0
   0 0 1 0 0 0
   0 0 0 0 0 0
>>> img.triplepoint().print()
   0 0 0 0 0 0
   0 0 1 0 0 0
   0 0 0 0 0 0
