Hello @eewse ,
For HLS, we are moving to the xfOpenCV libraries for support rather than the HLS optimized OpenCV libraries. I am not sure you have seen this location, but the example designs for xfOpenCV are located on GitHub here:
Unfortunately, I don't see one specific to that block matching algorithm. I also think this post may also be well read in the Video community, so will also move it there to get better visibility.
OK, sorry we don't have anything specific to this from a HLS perspective that I am aware of.

most of relative low grades xilinx boards will not have enough BRAM to run in ping-pong mode. But FIFO streaming(or dataflow) mode will pose stringent requirement on latency within xfopencv's sgbm.
I wonder whether there are anyone successfully to use xfopencv's sgbm in dataflow mode using Vivaldo HLS. I have some unconfirmed information that there are isolated successful cases using Bluespec's HLS and Mentor's HLS. I was told that both of them have a better latency insensitive support. Anyone can advise me whether I should seek alternative brand of HLS.
