The Fourth Workshop on Image Matching: Local Features and Beyond will be held at CVPR 2022 on June 20, 2022 (afternoon, Central Standard Time, USA). The workshop will once again feature an open challenge which will be announced in the following weeks. Further details will be announced before the conference.

Traditional, keypoint-based formulations for image matching are still very competitive on tasks such as Structure from Motion (SfM), despite recent efforts on tackling pose estimation with dense networks. In practice, many state-of-the-art pipelines still rely on methods that stood the test of time, such as SIFT or RANSAC.

In this workshop, we aim to encourage novel strategies for image matching that deviate from and advance traditional formulations, with a focus on large-scale, wide-baseline matching for 3D reconstruction or pose estimation. This can be achieved by applying new technologies to sparse feature matching, or doing away with keypoints and descriptors entirely.

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.
  • Leveraging additional cues such as semantics and mono-depth estimates.
  • Methods addressing adversarial conditions where current methods fail (weather changes, day versus night, etc.).
  • Attention mechanisms to match salient image regions.
  • Integration of differentiable components into 3D reconstruction frameworks.
  • Connecting local descriptors/image matching with global descriptors/image retrieval.
  • Matching across different data modalities such as aerial versus ground.
  • Large-scale evaluation of classical and modern methods for image matching, by means of our open challenge.
  • New perception devices such as event-based cameras.
  • Other topics related to image matching, structure from motion, mapping, and re-localization, such as privacy-preserving representations.

The last two editions were livestreamed on YouTube and remain available: 2020, 2021.
