pianke (Apr 24 2022 at 04:00): pianke (Apr 24 2022 at 04:00):I have three pixels x y z.Pixel x and y are neighbourhood and pixel y and z are also neighbourhood. On what basis/hypothesis I can say pixel x and z are neighbourhood. Please someone help me in clearification of this point.
Michael Soegtrop (Apr 24 2022 at 07:20):This depends on what you mean by neighborhood. Something based on distance? Something based on connectedness via other pixels in a set of pixels? Something based on general topological concepts?
pianke (Apr 24 2022 at 11:43):based on unit distance. I am confuse about the distance between two points .x , y and y ,z are possible . But how x and z is possible?
Michael Soegtrop (Apr 25 2022 at 07:50):If you define neighborhood based on a fixed maximum distance, it will obviously not be transitive. Say if pixels x and y and y and z both have a distance of 1, the distance between x and z could be 2. All you can do is that you say x and z are neighbors based on a more relaxed distance relation. Something like:
Neighbor d1 x y -> Neighbor d2 y z -> Neighbor (d1+d2) x z
Thank you .
