()-indexing must appear last in an index expression.

I have this formula. I interested in a DCP. but I want to find atmospheric light with this formula, not function.

for i=1:1:w
    for j=1:1:h
        A(i,j)=(min(Idark(i,j)>= A(i,j-1))(min(Idark(i,j): A(i,j-1))));
    end
end

(w,h image size)

I write like this but it gives the error.( ()-indexing must appear last in an index expression.) can you help me

[Ridwan Alam]

can you explain what this equation is representing? the way you implemented it is not correct.

[Fabio Corres]

where (i, j ) is the coordinate of image. A is simply equal to the minimum of Ω(i, j ) whose value is the largest in the scanned image.

Answer 1

[Ridwan Alam]

for i=1:1:w
    for j=2:1:h
        if (min(Idark(i,j))>= A(i,j-1))
            A(i,j)=min(Idark(i,j));
        else
            A(i,j) = A(i,j-1);
        end
    end
end

You've got closing and opening parentheses next to each other:

MATLAB thinks you are trying to use the second part as indexing or function arguments into the first part. This is what you need to fix.
