Activity8 – Morphological Operations

Structuing elements:
upper left:4x4 pixels square
upper right: 2x4 pixels
lower left: 4x2 pixels
lower right: 5pixels length 1 pixel width cross















50 x 50 pixel square dilated with the structuring elements as above.

the 1st square has an area of 2809 (53x53), meaning the original image has expanded by 3 pixels.
the upper right and lower left both have areas of 2703 (53x51 or 51x53). its orientation is dependent on the dimensions of the structuring element.
















50 x 50 pixel square eroded with the structuring elements as above.















50 x 30 triangle dilated with the structuring elements as above.











50 x 30 triangle eroded with the structuring elements as above.
















25-pixel radius circle dilated with the structuring elements as above.
upper right circle elongated vertically while the lower left circle elongated horizontally.the lower right circle has both horizontal and vertical elongation.















25-pixel radius circle eroded with the structuring elements as above.
upper right circle looked like it has been elongated vertically because there more parts have been eroded along the horizontal. same principle applies to the lower left circle. the lower right circle has both horizontal and vertical erosion
