Developing high-performing machine learning algorithms requires large amounts of annotated data, which can be costly and labor-intensive to manually annotate. Researchers have provided a curated set of fish image data with necessary software tools for generating synthetic images and annotations, facilitating the testing of classifier performance.
Developing high-performing machine learning algorithms requires large amounts of annotated data. Manual annotation of data is labour-intensive, and the cost and effort needed are an important obstacle to the development and deployment of automated analysis. In a previous work, we have shown that deep learning classifiers can successfully be trained on synthetic images and annotations. Here, we provide a curated set of fish image data and backgrounds, the necessary software tools to generate synthetic images and annotations, and annotated real datasets to test classifier performance. The dataset is constructed from images collected using the Deep Vision system during two surveys from 2017 and 2018 that targeted economically important pelagic species in the Northeast Atlantic Ocean. We annotated a total of 1,879 images, randomly selected across trawl stations from both surveys, comprising 482 images of blue whiting, 456 images of Atlantic herring, 341 images of Atlantic mackerel, 335 images of mesopelagic fishes and 265 images containing a mixture of the four categories.
