Practical implementation of real-time fish classification from acoustic broadband echo sounder data

Abstract

Figure ES.2: Screenshot of the Graphical User Interface (GUI) of the demonstrator, used on board by the skipper. Panel A: streaming echogram display. The display of the data can be changed using options the control panel (Panel C). Panel B: classification display, showing the detected schools and the estimated species type by the classifier Panel C: control panel with the different visualization settings that can be selected by the user. Visualization settings are: different Wide Band Transceiver (WBT) to visualise; change in colour scheme; filtering of the echogram; number of pings to display. Panel D: visualisation of length estimation results. This feature is not implemented yet. Panel E: Disturbance analysis panel, displaying a frequency spectrum computed on the detected interferences in the echograms. This indicates the operating frequencies of narrowband interferences (other sonars).
