Towards Generalized Multimodal Homography Estimation

arXiv – CS AI|Jinkun You, Jiaxin Cheng, Jie Zhang, Yicong Zhou|
🤖AI Summary

Researchers propose a new training data synthesis method for homography estimation that generates diverse image pairs from single inputs to improve AI model generalization across different visual modalities. The approach includes a specialized network design that leverages cross-scale information while decoupling color data from structural features.

Key Takeaways
  • Current homography estimation methods fail when applied to unseen visual modalities despite high accuracy on trained data.
  • New synthesis method generates unaligned image pairs with ground-truth offsets from single input images.
  • The approach preserves structural information while adding diverse textures and colors for better training data.
  • Specialized network design decouples color information from feature representations to improve accuracy.
  • Extensive experiments confirm improved generalization performance across various domains.
