A Realistic Fish-Habitat Dataset to Evaluate Algorithms for Underwater Visual Analysis

1 code implementation28 Aug 2020 Alzayat Saleh, Issam H. Laradji, Dmitry A. Konovalov, Michael Bradley, David Vazquez, Marcus Sheaves

The dataset consists of approximately 40 thousand images collected underwater from 20 \green{habitats in the} marine-environments of tropical Australia.

Data-Efficient Classification of Birdcall Through Convolutional Neural Networks Transfer Learning

1 code implementation17 Sep 2019 Dina B. Efremova, Mangalam Sankupellay, Dmitry A. Konovalov

In this research, we evaluated the effectiveness of birdcall classification using transfer learning from a larger base dataset (2814 samples in 46 classes) to a smaller target dataset (351 samples in 10 classes) using the ResNet-50 CNN.

Automatic Weight Estimation of Harvested Fish from Images

no code implementations6 Sep 2019 Dmitry A. Konovalov, Alzayat Saleh, Dina B. Efremova, Jose A. Domingos, Dean R. Jerry

The two CNNs were applied to the rest of the images and yielded automatically segmented masks.

In Situ Cane Toad Recognition

no code implementations9 Jun 2019 Dmitry A. Konovalov, Simindokht Jahangard, Lin Schwarzkopf

Cane toads are invasive, toxic to native predators, compete with native insectivores, and have a devastating impact on Australian ecosystems, prompting the Australian government to list toads as a key threatening process under the Environment Protection and Biodiversity Conservation Act 1999.
