Love timm, but need to do lower-level vision tasks? Meet IMM, a collection of Image Matching Models unified by a simple, easy to use API. You can use any of 30 models (LightGlue, LoFTR, RoMa, SIFT) just by cloning the repo and changing a single parameter! github.com/gmberton/image…

In case you missed it, NASA has published over 12,000 photos from the Artemis ii mission. This one included. Check them out here: eol.jsc.nasa.gov/SearchPhotos/S…

@davnords @zhenjun_zhao @gabriberton @isaaccorley_ @Parskatt @ducha_aiki I see it as a nice to have as well, in case someone wants to order kpts to take top N or similar. or take a secondary (higher) threshold w/o rerunning the matcher. It's available in ~30-50% of the matchers, off the top of my head.

@zhenjun_zhao @gabriberton @AlexStoken @isaaccorley_ @Parskatt @ducha_aiki I have never used it as weighting for a robust solver. RoMa v2 has this precision matrix which was used in conjunction with PoseLib though. For me it does not feel important for the vismatch api to return some score. Feels excessive. But I am new to matchingworld :)

Gabriele Berton@gabriberton·1d

Image matching folks / VisMatch users: How important is it to provide the score of each match? Not all methods return a score but we could support it for those that do

We are training a SotA rotationally robust matcher. Currently thinking about what to train for. Comment below your top use-cases for image matching that need more love!

When @davnords @Parskatt release a new SoTA matcher, we try to get it on pypi as soon as possible! Thanks to @davnords for the PR. Currently the easiest way to use LoMa-R, the rotation invariant version 🔄

Gabriele Berton@gabriberton

VisMatch 1.2.1 is out! And it includes the state-of-the-art matcher LoMa! Congrats and thanks to @AlexStoken @davnords @Parskatt

@gabriberton @davnords @Parskatt @zhenjun_zhao @isaaccorley_ Their is also a bunch of orthomosaics from Landsat/sentinel with really reliable per px location, which can make for easy GT. Good for seasonal variation, but will need the ISS photos or data aug for perspective change 😉 but I ofc course thing this is a great idea

English

Gabriele Berton@gabriberton·15 Nis

@davnords @AlexStoken @Parskatt @zhenjun_zhao @isaaccorley_ Yes please! I can share plenty of satellite + ISS data if you want. The ISS images have plenty of natural data augmentation which should make a dedicated matcher super strong

@gabriberton @Ichsan2895 Ya I have some spaghetti code for this that needs organizing, but would also love to see a PR!

Gabriele Berton@gabriberton·20 Mar

@Ichsan2895 We thought about it with @AlexStoken but did not implement it yet. Would you like to work on it and do a PR?

VisMatch is on pypi! VisMatch is a wrapper for image matching models, like LightGlue, RoMa-v2, MASt3R, LoFTR, and 50+ more! It's literally as simple as: pip install vismatch vismatch-match --inputs img0 img1 --matcher choose_any To run image matching on any 2 images [1/4]

Vismatch (formerly image-matching-models) is out on pypi! One line install, one line matching, one simple API. Very excited about this milestone after some awesome recent updates in collab with @gabriberton @ariG23498 !

A good detector can make or break your spacecraft localization pipeline, and this is a great opportunity to try your hand at designing a SOTA, generalizable detector!

In cis-lunar space, craters are descriptive, reliable landmarks for pose-estimation. They have distinct shapes and can be matched to a compact catalog of known craters.

@AlexStoken @gabriberton @ariG23498 @motokimura1 Sounds good, fwiw in torchgeo we also put all model weights in hf and so far so good.
