Disclaimer: This is my first real time using Gimp, so I apologize if this is a basic question.
I'm trying to blend the colors of my pixels together based on the neighboring pixels. For example, consider the following 9 pixels.
0 1 2 3 4 5 6 7 8
Suppose that each number represents a value in a color channel. I'm looking for a tool such that given a pixel p, p's new value will the average of its (at most 8) surrounding pixels and itself.
The new values of the pixels above should be, after rounding:
2 4 3 4 4 5 5 6 6
Can someone point me towards a tool that can help achieve this?
