at 58:06 it must be A erosion with B1

This lecture follows the book Digital Image Processing - third edition - Rafael C Gonzalez. Chapter 9

[@tasneemkaka1942]

hey. Suppose we use the second definition of erosion. Let the origin of W-X be at the center of W-X. When we place the origin on the top pixel from the two pixels on the left hand side of the result of (A erosion with X), W-X overlaps the bottom of the original left hand side image which means that in this position W-X is not a subset of the compliment of A, hence the origin in this position is not included in the result. Likewise happens if the origin of W-X is placed one pixel below.

Thank you for that lecture, the demonstration of the properties was very useful! Thank you

Thank you sir this lecture series helped me a lot.

In hit or miss transform when we do the compliment of A and erode it with W-X how only 1 pixel is remaining..I am unable to understand it..If any one can explain this..

[@saidineshyada4927]

Consider how to create the right Hit and Miss masks to detect:
a. Horizontal lines of the length 4.
b.vertical lines of the length 2 or 3.
c.right lower corner
Can someone answer this questions?
