Consider the attached labeled image of 10 objects. Each object is denoted by a numeric value 1-10.
I want to count adjacent objects for each that it shares a border with. For example for object 2 it shares the border with 1 and 3. So input will be 2 and output will be 1 and 3.
For the case of 7. Input 7, Output 3,4,6,8,9,10

This can be done with graycomatrix(). Trust me. Please think about it and try it yourself first.

Thanks, It worked... Just few lines of code for other help:
glcms=graycomatrix(Labled Image);
kkkk=glcms(:,SupNum); %if you want to find neibours of 1,then input SupNum=1
[rrrr,~]=find(kkkk>0); aa=find(rrrr==SupNum); rrrr(aa)=[];
%%rrrr is output matrix which contains the neighbours of 1(or your desired one)
