Minor modification to the rules on descriptor size
In order to allow submissions of papers/methods that do not have a clear feature size, such as those relying on dense feature maps, we have chosen to remove the 128D limit on the descriptors. Note that this will allow you to use models like SuperPoint or D2-Net. It comes with the following caveats:
- If your method relies on descriptors, you should still add the descriptor files, even when submitting custom matches. This allows us to check the correctness of the submission. If this is simply not possible with your method, you may omit the descriptor files — but only then.
- If you make a submission with descriptors larger than 128D, you must submit your own matches, instead of using the built-in matcher. This is required in order to keep our compute budget in line.
