Image of template used in spectrogram cross correlation in the first algorithm. The white line is the frequency trend of a high SNR call, the black values are the padded spectrogram template area and the grey areas are the locations used for comparing noise levels above and below the fin whale pulse frequency band (14.6 Hz, to 29.3 Hz).
