Gravitational-wave excess power searches are often framed in terms of finding structure in a spectrogram, or ft-map, with a pattern recognition algorithm. Here, we describe one such pattern recognition algorithm, burstegard. We demonstrate the ability of this algorithm to identify structure due to simulated gravitational-wave signals in an ft-map.
