Exercise 3: Image Filtering

This exercise uses mean and median filters with different kernel configurations to get the image.


Kernel 1

Mean Filter

Median Filter

Not much can be seen from this image as they can both be used to filter the image. the higher the value of kernel size, the bigger the difference can be in terms of blurring the edges.



Kernel 2

Mean Filter

Median Filter

The median filter is lighter compared to mean filter. Also, the banana has more violet spots in the mean filter which correlates to the nature of what a mean is.



Kernel 3

Mean Filter

Median Filter

In the mean filter, you can still see the edges, but its darker. While in the median filter, the edges can be disregarded as you cannot see it.



Kernel 4

Mean Filter

Median Filter

The mean filter is same with kernel 3 but blurrier. The edges are scattered. The median filter is same with kernel 3.



Kernel 5

Mean Filter

Median Filter

The mean filter is buzzing with noises scattered to the places where this is much edges. As you can see, the surroundings of the banana is dark.
The median filter made the image turn negative.


That is all.
