finding the corresponding value in a for loop

Hi,

I have created a for loop which loops through a number of columns on the image and finds the number of times that 0 (black colour) occurs in that column

for b=1:50
   [c]=numel(find(img597(:,b,1)==0))
end

How do I find the corresponding value ( the column) where the maximum number of 0s has occured. The answer has to be 50

the easiest way is to use

nrOfZeros=sum(img597(:,:,1)==0);

which gives you a row vector containing the number of zeros per column

colNrs=find(nrOfZeros==max(nrOfZeros),sum(nrOfZeros==max(nrOfZeros)))

colNrs then contains the numbers of columns with the maximum number of 0

This is to find axis from an image. I am looping for the size of the number of columns to find the x axis and am looking to the same and find the y axis? how would I do that?

[Jonas]

it's the same procedure but with the first snippet being

nrOfZeros=sum(img597(:,:,1)==0,2);

which gives you a column vector with the number of 0 per row

[~,idx]=max(sum(img597==0));
