In his thesis, Martin Mathias Nielsen introduces methods to support automated documentation of catches onboard commercial trawlers. Accurate data on catches is a crucial element in assessing the impacts of fisheries on fish stocks which helps managers implement appropriate actions to secure the long-term sustainability of fish stocks.
Electronic monitoring cameras installed onboard fishing vessels combined with deep learning algorithms have emerged as a promising solution for providing and analyzing such data. In his thesis, Martin Mathias Nielsen introduces several methods to help analyze catch compositions in terms of species, counts, and length estimations, in complex catch scenarios with overlapping catch items.
A critical contribution of his thesis is the development and application of a novel methodology for collecting datasets for video instance segmentation in complex catch scenarios onboard fishing vessels. The collected benchmark dataset, which is publicly available, contains ground-truth information on species, length, and visibility level for each individual catch items, making it the first of its kind in fisheries.
