“…vessels). Some papers deal with “inshore vessel detection” in ports and in inland waters (Beşbinar and Alatan, 2015, He et al, 2017, Hu et al, 2015, Li et al, 2016, Li et al, 2016, Liu et al, 2014, Ren et al, 2015, Xu et al, 2014), which, as opposed to vessel detection on open sea, has to cope with high similarity between vessels and port background in terms of colour and structure (Beşbinar and Alatan, 2015).
