ECU-MSS-2 dataset, a new multi-species seagrass dataset

Full description

The "ECU-MSS-2' dataset contains four different habitats, 'Amphibolis' spp (hereafter 'Amphibolis"), 'Halophila' spp (hereafter 'Halophila'), 'Posidonia' spp (hereafter 'Posidonia') and 'Background'. We compiled this image dataset from different sources. The 'Halophila' images were collected by the Centre for Marine Ecosystems Research, Edith Cowan University, Western Australia.

The 'Amphibolis' 'Background' and 'Posidonia' images were collected by the Department of Biodiversity, Conservation and Attractions (DBCA), Australia. The 'Amphibolis' class includes the seagrass species Amphibolis griffithii and Amphibolis Antarctica. The 'Halophila' class includes Halophila ovalis, while the 'Posidonia' class includes Posidonia sinuosa, Posidonia coriacea, and Posidonia Australis. The 'Background' class includes coral, sand, sponge, seaweeds, fish and other benthic debris.

The dataset contained total 5,201 images, where the 'Amphibolis' class has 1304 images, the 'Background' class has 1237 images, the 'Halophila' class has 1315 images and the 'Posidonia' class has 1345 images. The total images were divided into training and test sets. The training set has 4,161 images and the test set has 1,040 images. All four classes have the same 260 images in the test set.
