Echofilter is an application for segmenting an echogram. It takes as its input an Echoview .EV file, and produces as its output several lines and regions:
turbulence (entrained air) line
passive data regions
*bad data regions for entirely removed periods of time, in the form of boxes covering the entire vertical depth
*bad data regions for localised anomalies, in the form of polygonal contour patches
Echofilter uses a machine learning model to complete this task. The machine learning model was trained on upfacing stationary and downfacing mobile data provided by Fundy Ocean Research Centre for Energy (FORCE.).
Disclaimer
The model is only confirmed to work reliably with upfacing data recorded at the same location and with the same instrumentation as the data it was trained on. It is expected to work well on a wider range of data, but this has not been confirmed. Even on data similar to the training data, the model is not perfect and it is recommended that a human analyst manually inspects the results it generates to confirm they are correct.
* Bad data regions are particularly challenging for the model to generate. Consequently, the bad data region outputs are not reliable and should be considered experimental. By default, these outputs are disabled.
Integration with Echoview was tested for Echoview 10 and 11.
