All Patches

Each annotation is cropped to a 640×640 patch; larger annotations are scaled to fit. Nearby objects share a patch, so the same object can appear in more than one image. Duplication is kept to a minimum: an object is only added if it is not already covered. Labels at the edge of a patch may be cropped.

Access

The full set is close to 500 GB, so we do not keep a public download online. Write to with the subset you need (original RAW, half size, or patches) and a short note on how you plan to use it, and we will send you a transfer link.
