MATLAB: How to extract a distribution from a 2d histogram

How can I extract a distribution from a 2d histogram?

Good morning,

I have created a 2D histogram. That is straight forward, I have the 3 matrix, X Y the grid and Z, the number of counts in each cell of the grid.

Now it comes my question, the big histogram, (that you can see in the attached photo) gives me a lot of information but I need the marginal histogram, for example I want to know the number of counts (Z) but only along the line y=-2x+1.

Can you give me a bit of help?

Thank you very much in advance

 P = sortrows(P,7) ;

Most of the time functions don't operate "externally", so SORTROWS doesn't alter your array P defined in the workspace. It creates a new sorted array that it outputs. You have to store this output back into P if you want P to be the sorted version. If you wanted to keep the original, you could store it into a new variable:

 P_sorted = sortrows(P,7) ;

MATLAB: Difficulty finding euclidean distance to match

What you're calling the Euclidean distance is the RMS difference in intensity between the two images. And that (and PSNR and MSE) is not such a great way to compare images anymore, unless you're looking for a fairly exact match - like you know for a fact that the test image is definitely one of the database images. You'll probably find SSIM is used more often: http://en.wikipedia.org/wiki/SSIM. But I can't run your code because I don't have the Wavelet Toolbox. I've added it to the product list to alert anyone else who might try to run your code.
