Eliminate the pixel that have a lower intensity?

I read the immage in this way:
m=max(Imm,[],'all');
%Threshold
thr=10;
for i=1:2048
for j=1:2448
if Imm(i,j)>(m-thr)
pos(k,1:2)=[i,j];
k=k+1;
end
end
end
"Pos" contain all the pixel of my intrest, now i want to elimintate all the coordinates of the pixel that have intensity lower than a value

You don't need a for-loop for this
m=max(Imm,[],'all');
%Threshold
thr=10;
[r,c] = find(Imm>(m-thr))
pos = [r c];
By elimination, if you mean to set them to zero, then try this
m=max(Imm,[],'all');
%Threshold
thr=10;
Imm(Imm<(m-thr)) = 0;

I didn't understand the question. Can you take 2 small 3x3 matrices and show with an example of what you want?
