Hello,
I've been working on trying to get the STEREO_GIF algorithm to run with OpenCL. It doesn't seem to work directly out of the box. Has anyone had success accomplishing this? It seems like the non-OpenCL stuff runs great.

I already have calibrated and rectified left and right image as opencv Mat. I am currently using sgbm module for finding depth map and for post processing.

What is expected fps for a disparity map for image 640x480 with post processing?

Can you provide instructions for which functions of your code (minimalist) if I need opencl based stereo matching and post processing, which I plan to run on Odroid SBC?

On Ubuntu 16.04, after building, and using this command below the output window appears and freezes...

BTW runninag as sudo since it gives OpenCL error: CL_OUT_OF_RESOURCES error if not.
