A = imread('thank-you.jpg');
[iRows, iColumns, ~] = size(A);
for iLoop1=1:iRows
for iLoop2=1:iColumns
B(iLoop1, iLoop2) = max(A(iLoop1, iLoop2, :));
end
end

I dont know any direct way, but you can run a loop on the length and breadth of the image matrix to find the max of R, G, B at each pixel.

l=size(A); for i=1:l(1) for j=1:l(2) a=A(i,j,1); b=A(i,j,2); c=A(i,j,3); C1=max(max(a,b),c); end end This is the code I used But it didn't work.Can you rectify it
