Understanding Structuring Element with Trackbars

As we already discussed that the most important thing in morphological image processing is the Structuring element. This is used to probe an image for finding the region of interest. Different shapes and sizes of SE will produce a different result. Thus it becomes vital to have a good grasp on this for better understanding of morphological image processing. In this blog, let’s create trackbars which makes it really easy to visualize the result for different values. So, let’s get started.

Steps:

  • Load the image and create a window to attach trackbars
  • Specify the morphological operations and Structuring elements
  • Create the trackbars and the callback function

This will produce the following output

Play with the trackbars to get a feel about the morphological operations. That’s all for this blog. Hope you enjoy reading.
