About

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.

The workshop topics include (but are not limited to):

• Reformulating keypoint extraction and matching pipelines with deep networks.
• Applying geometric constraints into the training of (sparse or dense) deep networks.
• Leveraging additional cues such as semantics.
• Developing adversarial methods to deal with conditions where current methods fail (weather changes, day versus night, etc.).
• Exploring attention mechanisms to match salient image regions.
• Integrating differentiable components into 3D reconstruction frameworks.
• Matching across different data modalities such as aerial versus ground.

Challenge

We have renewed the challenge for last year, with many changes. The framework has been open-sourced, and we have greatly improved the evaluation server. For details, please refer to the challenge website.

Paper Submission

We welcome full paper submissions and extended abstracts, which will be presented in the workshop as posters. Please refer to the Call for Papers.
