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.
