Activity9b

2nd image(658x823)



















1 part of the image (1/12)(256 x 256 pixels)















processed image of the part above. the structuring element used is the same structuring element used in the first part (cross)

average area:

471.8495

pixel counting area:

435.8

error: 8.2 %









rating:9/10 -the error for the 2nd part is quite high, another structuring element might lower the uncertainty for this part.

Activity9a

original image (748 x 618 pixels)















(1/9) one part of the original image (256x256, lower right)


















image processed result
the structuring element used was a cross with 5 pixels length and 1 pixel thickness

the process was done 9 times using 9 different parts of the image
average size:

519.8939

calculated average area of 10 full circles from different parts of the image using pixel counting:554.6


error: 6.25%

Activity8 – Morphological Operations (continuation)

hollow square dilated with the corresponding structuring elements.

the thickness of the width in the lower right and upper left images varied depending on the orientation of the corresponding structuring image used.
