Hi everyone, I am working on image processing. I want to find LBP on different scales. by

firstly adding neighbors on each scale/radius (by taking average of every 2 or 3 .. pixels and make them 8) then concatenating scales and for final LBP code i have to consider 8 neigbhoring points.

but on R1, neighboring points=8

on R1, neighboring points=16,

R1, neighboring points=24

an so on..

now how to access 16 ponts on R2, to make them 8 by taking average of every two points.

I try to explain it in simple words. can anybody help to code this.

Regards.

sir, my task is to take average of neighboring pixels at different scale and make them 8. and then adding all cosidered radius/scales. befor further processing. but i cant understand how to access all pixels of different scales seperately, for averaging them.

for simplicity in example considered Radius is R1 and R2. but R can be any positive value.
