SIFT keypoints number and descriptors in fundamental model about oanet HOT 4 CLOSED

It is normal to get less than 8k points.
Which fundamental model do you use? The model trained on GL3D?

Ok, I am using the model trained on yfcc100m.

from oanet.

This model is trained using --use_fundamental=True --geo_loss_margin=0.03 --use_ratio=2 --use_mutual=2. You might need a 24G GPU to train this model, or you need to decrease the batch size and increase training iters.

So it is not the problem of sift extraction process . Maybe I just forgot to set above parameters. Thanks for your reply.
