Vortex Vision Training Data

Multi-scale vortex structure training images for the vortex-vision CNN/GNN pipeline.

Overview

This dataset contains labeled images of vortex structures across physical scales, from atmospheric phenomena (tornadoes, waterspouts, jellyfish clouds) to astronomical objects (nebular pillars, proplyds, filaments). The goal is to train a neural network that identifies vortex morphologies (columns, rings, braids, Y-junctions, X-crossings, kinks) independent of scale and medium.

Catalog

The catalog metadata (object definitions, observation records, feature annotations) is maintained in the main vortex-vision repository under data/catalog/ and data/annotations/. Image filenames in the catalog reference paths in this dataset.

Vortex Feature Taxonomy

• Column: Elongated vortex filament
• Ring: Toroidal vortex (ring vortex)
• Braid: Two or more filaments wound around shared axis
• Y-junction: Three filaments meeting at a point (merge or split)
• X-crossing: Two filaments crossing/reconnecting
• Kink: Sharp bend in a filament (possibly from embedded ring)
• Kelvin wave: Helical oscillation along a filament
• Virga: Entrained material draping from a ring vortex
