Data sources and licenses
Brikamo's brick recognition models were trained only on open datasets whose licenses allow commercial use (CC0, CC BY, MIT, Apache 2.0), and on photos taken by the app's creator. Thank you to all the authors.
Datasets under CC BY 4.0 were changed: images were cropped, resized and saved with boxes in a different format. The dataset authors do not endorse Brikamo. License texts: CC BY 4.0 · CC0 1.0 · MIT · Apache 2.0.
