repeatable keypoint #9

Open szgy66 opened 2 years ago

Hi，I read your paper "TILDE: A Temporally Invariant Learned DEtector", the article repeatedly says the repeatable keypoint, and I want to ask what does repeatability mean? At the same time, I also want to ask, for a series of images from the same viewpoint, sift is used to extract features, so whether to find the points in all images or to combine the points in all images. thanks!

Hi,

as discussed in Section 5.2, we use the definition as in [31],

As in [31] we consider keypoints that are less than 5 pixels apart when projected to the same image as repeated.

You can also look at other works that define repeatability via overlap measures as well.

so whether to find the points in all images or to combine the points in all images.

I don't understand your question. Sorry.
