MATLAB: How to get the limits of the highest frequency bin in a histogram

histogrammax

Hello,

Is it possible to get the limits of the highest frequency bin in a histogram?. For example, in the attached figure, I have a histogram of three bins where the width of each bin is 1 and the bin of highest frequency is the second bin which is [0,1]. So, I need to write lines of code that find the highest frequency range of values which is here [0,1].

Regards,

[counts,binLocations]=hist(data);
%find the bins of max(counts)

Then previous value & next value are limits

Normalization would mean that you either divide by the max value of the counts, or that you divide by the sum of all the counts.

[pixelCounts grayLevels] = imhist(lbpImage, 256);
normalizedHist1 = pixelCounts / max(pixelCounts(:));
normalizedHist2 = pixelCounts / sum(pixelCounts(:));

It means that either the max value of any count will be 1.0, or that the sum of all counts would now be 1.0, depending on which method you use.

You only need to ask imhist to output those data:

[counts,binLocations] = imhist(I)
