I want determine the picture with the highest mean from a set of images loaded
into matlab as matrix. The code is below. I want to know the exact picture with
the highest mean so as to make it as a basis for further calculation. This
should be printed out.
for k = 1:length(jpegFiles) % loop to run large number of pictures
filename = jpegFiles(k).name;
data = imread(filename);
y = mean(mean(data));
end
Determine highest mean from set of images

Hello,
The code you have seems pretty good, I would suggest making the 'y' variable
a vector. y(k). Make sure for speed to reallocate the space for the
variable. Then you can use the Max function to give the max mean and the
indices which it belongs to.
I think that should work,
