DOI: 10.1109/tcsvt.2024.3502170

Abstract: Homography estimation is essential for aligning images captured from different viewpoints by accurately modeling the geometric relationship between them. In homography estimation, global information plays a critical role. To establish global correspondences, cross-attention has been… read more here.

DOI: 10.1109/tpami.2022.3223789

Abstract: In this paper, we introduce a new framework for unsupervised deep homography estimation. Our contributions are 3 folds. First, unlike previous methods that regress 4 offsets for a homography, we propose a homography flow representation,… read more here.

DOI: 10.1109/tpami.2024.3366234

Abstract: Multi-modal homography estimation aims to spatially align the images from different modalities, which is quite challenging since both the image content and resolution are variant across modalities. In this paper, we introduce a novel framework… read more here.

DOI: 10.1364/ao.444847

Abstract: Existing feature-based methods for homography estimation require several point correspondences in two images of a planar scene captured from different perspectives. These methods are sensitive to outliers, and their effectiveness depends strongly on the number… read more here.

DOI: 10.1364/ao.57.003316

Abstract: The homography matrix is crucial for many optical metrology applications, such as three-dimensional surface imaging by structured-light projection. In this paper, a straightforward homography estimation method using the image of three particular points on the… read more here.
