Point Location
The Point Location module provides a quick way to identify specific coordinates within the image based
on their location. For example, you may want to know the position of the highest point of any non-black
pixel within the image to identify a maximum peak. Note that this module operates on a binary
image.
The module is often used after numerous morphological operations that have binaried and changed
the image shape.
Note that the north, south, east, west points are calculated relative to the object's Center of Gravity point.
