Latest Patents

Tzagkarakis holds a patent titled "Joint wideband source localization and acquisition based on a grid-shift approach." This patent involves techniques for source localization and acquisition that utilize a wideband joint acoustic source localization method. The approach is grounded in a sparse optimization framework, employing an orthogonal matching pursuit-based grid-shift procedure. A specific grid structure is constructed, featuring the same number of grid points as the on-grid case, but shifted across the acoustic scene. This innovative method anticipates that each source will be located near a grid point in at least one of the shifted grids. The sparse solutions from these shifted grids are combined to provide accurate source location estimates, which are then used to recover the original source signals.
