This package provides implementations of several commonly used histogram
- Kullback-Leibler Divergence
- Jenson-Shannon Divergence
- Jeffrey Divergence
- (Histogram) Intersection
- (Histogram) Match
- Quadratic form
The package comes with an example of color image matching (although this might
not be the best application idea, imho; anyway, it showcases the code).
I have applied some of the histogram distance functions for outlier reduction
when learning color term/name models from web images, see:

If you use and like this code, you are kindly requested to cite some of
the work above.
@Muhammad: You should have a look in the section marked "match histograms and show best matching pairs" in hist_dist_example.m. In any case, the interface is compatible with Matlab's pdist2 function, which makes it fairly simple.
Hi, I want to compare two histograms , can you give Running Example from your code
I got an error running this, but
the fix is simple, the error and
the patch are below:

@K E: No. The distance functions should not depend on any other package/toolbox. As for the example in hist_dist_example.m, I think that squareform/pdist2 are part of the Statistics Toolbox, BUT you should be able to run it without the toolbox if you use the code block marked by "Use the following loop to calculate the distances, iff the measure is not symmetric" (just umcomment/comment the necessary code lines).
Do you need the Statistics Toolbox for these codes?
- switched http to https when downloading example images, patch provided by James Ganong
- I forgot to add the example script in the initial submission. Fixed.
