Limits RegistryThe Solar Filament Segmentation Challenge 2026 is a computer-vision competition with an advertised prize pool of up to $3,000.
The question, scope, and sources behind this Registry record.
Develop a computer-vision system that automatically segments solar filaments from the official GONG H-alpha observations under the 2026 challenge rubric.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
