Results for the first real signal of the dolphin sound, TFD of the original signal (a), obtained optimal entropy map from spectrogram (b), obtained optimal entropy map from RIDB (c), mask obtained from applying RICI threshold on spectrogram (d), mask obtained from applying RICI threshold on RIDB (e), and mask from applying fixed threshold of 10% on signal spectrogram (f)
