AstroHOG was created by Juan D. Soler, but is now maintained by several people. See the AstroHOG repository on GitHub for further details.
AstroHOG is set of tools for the comparison of extended spectral-line observations (PPV cubes). In essence, the histrogram of oriented gradients (HOG) technique takes as input two PPV cubes and provides an estimate of their spatial correlation across velocity channels.
