Several methods have recently been proposed to estimate the 3D positions of acoustic reflectors given room impulse responses (RIRs). In this article, we categorize these methods as \"image-source reversion\", which localizes the image source before finding the reflector position, and \"direct localization\", which localizes the reflector without intermediate steps. We present five new contributions.
