Dataset visualizations contextualizing FathomNet relative to ImageNet. (a) The average pixel values of images in ImageNet and FathomNet. Images from a midwater and benthic concept in ImageNet (hosted on Flickr) were approximately matched to concepts available in FathomNet, and an equal subset of images from both repositories were resized and averaged pixel-wise (far-right column). The uniform image patches from FathomNet suggest that there is more diversity in poses and object sizes relative to labeled data from ImageNet. FathomNet image credits: MBARI. (b) Concept coverage at different taxonomic ranks within FathomNet. Fifty FathomNet images were selected randomly at each level of the taxonomic tree and checked for annotation completeness by a human expert. Green bars correspond to the midwater concept Bathocordaeus mcnutti and blue bars correspond to the benthic concept Gersemia juliepackardae. Darker colors are the target concept and lighter colors are any other concepts present in the frame. Benthic images are typically missing more annotations than those from midwater habitats.
