SEED® 2020
BCE’s proprietary signal enhancement and event detection (SEED®) software allows for real-time signal enhancement, event detection, event dominant frequency estimation and ambient noise characterization. SEED® implements a state-of-the-art Bayesian recursive estimation technique which incorporates Kalman filtering, particle filtering, Rao-Blackwellized particle filtering and hidden Markov model (HMM) filtering.
