The final step is to build a graph-theoretic representation by identifying and keeping only the critical points (terminations, bifurcations, inflections) (36, 38, 53).
WebJan 16, 2024 · A statistical feature-extraction method based on a sliding window is proposed. An X-ray burst is a continuous process with states of rise, plateau, decay, etc. This algorithm can capture the variation of count rate in photon sequence in more detail, and the generated multi-scale feature matrices can provide more information.
