iPhone
See the stars in every picture!
Add Astra was our first app. It uses the Yale Bright Star Catalog with extracted image metadata (date, time, location, orientation, and direction) to find star positions accurate to your uploaded image. Add Astra also uses the DETRResnet50SemanticSegmentationF16 Machine Learning Model to find the sky in your image, and only overlay the stars there, so you don’t have weird white dots all over your picture!
