Workshop: https://image-matching-workshop.github.io
CMT website for paper submission: https://cmt3.research.microsoft.com/IMW2026


*Overview*

The 8th edition of the Image Matching Workshop is co-located as every year with CVPR 2026. Our goal is to encourage and highlight novel strategies for image matching that deviate from and advance traditional formulations, with a focus on large-scale, wide-baseline matching for 3D reconstruction and pose estimation.


*Challenge*

The workshop will once again feature an open challenge hosted on Kaggle. This year's challenge extends the previous year one with the purpose of serving as a reference dataset with a larger life span. Teams with best submissions will be invited to present their solutions at the workshop.

*Topics*

Workshop topics include (but are not limited to):
- Formulations of keypoint extraction and matching pipelines with deep networks.
- Application of geometric constraints into the training of deep networks.
- Large-scale evaluation of classical and modern methods for image matching, by means of our open challenge.
- Matching across different data modalities such as aerial versus ground.
- Leveraging additional cues such as semantics and mono-depth estimates.
- Attention mechanisms to match salient image regions.
- Connecting local descriptors/image matching with global descriptors/image retrieval.
- Methods addressing adversarial conditions where current methods fail (weather changes, day versus night, etc.).
- Integration of differentiable components into 3D reconstruction frameworks.
- New perception devices such as event-based cameras.
- Other topics related to image matching, structure from motion, mapping, and relocalization, such as privacy-preserving representations.


*Invited speakers*

- Paul-Edouard Sarlin, Google
- Nikhil Keetha, CMU / Meta


*Paper submission*

We invite paper submissions up to 8 pages, excluding references and acknowledgements. They should use the CVPR template (reviews are double-blind, so please hide author data in the pdf) and be submitted to the CMT site (linked above). Submissions must contain novel work and will be indexed in IEEE Xplore/CVF. They will receive at least two double-blind reviews.


*Important dates*

- Paper submission deadline: March 16, 2026.
- Notification to authors: April 6, 2026.
- Camera-ready deadline: April 8, 2026 (hard deadline on April 11).
- Workshop date: TBC (June 3 or 4, 2026).
