Activity 8: Morphological Operations

In this activity we were tasked to explore the properties of dilation and erosion by applying the said operations on a square, a triangle, a circle, a hollow square and a cross. We are to perform the operations using each of the following: 1) 4x4 square, 2) 2x4 rectangle, 3) 4x2 rectangle, 4) a plus sign of width 1 and length 5. My results are listed below. They are arranged in order of the operators above.

DILATION






EROSION

My predictions for the dilations were spot on except for the triangle dilated with a plus sign. I forgot to note that the bottom side should have manifested the plus sign as square 'clips'. As for the erosions, I was correct for all except the hollow squares. I thought the widths of the operators would have been enough to completely erode the corresponding edges. it seems however that except for the last case (the plus sign operator), thin lines still remained.

I give myself a grade of 9/10 because I was able to execute the procedure completely. My predictions were a bit off hence the -1.
