What algorithm does voxl-dfs-server use for depth estimation? Is it semi global block matching?

@KnightHawk06 , DFS on VOXL2 uses the Qualcomm's proprietary implementation of the DFS algorithm, which runs on the specialized DSP (CVP - Computer Vision Processor). Unfortunately we do not have any details about the actual algorithm.
