The process of understanding acoustic properties of environments is important for several applications, such as spatial audio, augmented reality and source separation. In this paper, multichannel room impulse responses are recorded and transformed into their direction of arrival (DOA)-time domain, by employing a superdirective beamformer. This domain can be represented as a 2D image. Hence, a novel image processing method is proposed to analyze the DOA-time domain, and estimate the reflectiondoi:10.1109/icassp.2018.8462146 dblp:conf/icassp/RemaggiKJFH18 fatcat:llktikcow5fkbjkjw4d7p6oufi
