How to implement an histogram in a FPGA device??

I need to implement an histogram in a FPGA for 2D image frames. Any suggestion or reference design??? Thanks in advance.

For the mode, don't you just find the histogram bin with the highest value in?

At the end of the frame, go through each address in the histogram with a counter and latch the address and data values if the data is bigger than your previous "biggest value".

Cheers
