Fish-Vista in FiftyOne: Exploring Museum Fish Specimens

The blog post discusses Fish-Vista, a dataset comprising 60,000 images of museum fish specimens across 1,900 species, utilized to explore and test the capabilities of the FiftyOne tool, particularly in segmentation and taxonomy. Unlike the Community Fish Detector (CFD) used in Part 1, which focused on detecting fish in diverse underwater environments, Fish-Vista allows for species classification, trait identification, and pixel-level segmentation of nine anatomical structures. The study found that a detector trained on wild footage could effectively identify fish in the high-quality museum images without fine-tuning, achieving a mean average precision (mAP) of ~0.97. This cross-domain robustness highlights the potential of using field-trained models for auto-annotation in a different modality. The blog also emphasizes the ability of FiftyOne to work with imbalanced species data and how it facilitates comparative anatomy through trait masks, enabling users to perform complex queries and analyze species morphology efficiently.
