Activity 8 - Morphological Operations

In this activity, basic morphological operation is introduced. The first operation is by erosion. In image erosion, images are being thinned according to the structuring element that is used. The second is image dilation. Dilation allows the image to cover more area based on the structuring element.

Before simulation, these to operations are solved manually. Shown below are the simulations for these two operations. First is erosion.

The first column is the original image, the second is for an SE = 4 x 4 ones, third is for 2 x 4 ones, fourth is for 4 x 2 ones and lastly is for a cross that is 5 pixels long and one pixel thick.

My predictions matched for the square, triangle and circle patterns. But for the hollow square and cross, my prediction are not as accurate. This is because I thought that there will no side lengths in the 2nd to last SE because i thought that the sides will be completely removed. For the cross, I didn't expect the last pattern for the cross SE.

Almost all of my predictions are correct in the Dilation of images. The hard one is on the pattern triangle where there will be no pointed corner.

I give myself 10 points for finishing and understanding the activity.
