This example demonstrates how to use algorithm on regions. For a general understanding of regions, have a look at the Image Region from file example.
A region can be dilated and eroded by using a structuring element. The structuring element is defined as a region itself. Note, that the structuring element must not be inside the image coordinate system. It has its own coordinate system, which may even start negative. In this example a structuring element in form of a rectangle is used:
x: -1
y: -1
width: 3
height: 3
The following images are scaled for visuals.
The region is displayed in red.

Image with eroded region:
This example depends on the following components:
- IDS peak standard Setup version 2.19 or later
- CMake version 3.10 or later
- A supported C++ compiler (MSVC, GCC, or Clang)
