How to generate 2D Cr-Cb Histogram for auto white balance?

Hi,

 

We need to implement 'Auto white balance' Feature using CCM IP core . We are referring xapp794 . 

In xapp794 , Auto white balance is implemented using 2-Dimensional Cb-Cr Histogram and 2-D histogram is provided by Image Statistics IP.

 

Image Statistics IP is discontinued now . So, we implemented histogram generation by our self .

We can generate 1-Dimensional - Y , Cr or Cb Histograms. But, don't know how to generate 2D Cr-Cb histogram .

 

Anyone knows how to generate 2D Cr-Cb Histogram for auto white balance?
