Hybrid Focal Stereo Networks for Pattern Analysis in Homogeneous Scenes
, 2013 In this paper we address the problem of multiple camera calibration in the presence of a homogeneous scene, and without the possibility of employing calibration object based methods.

Pano‐Matching: Panoramic Local Feature Matching Using Interconnected Dynamic Transformer
IET Image Processing, Volume 19, Issue 1, January/December 2025.We propose a new panoramic detector‐free matching approach, called pano‐matching. Experimental results on multiple datasets show that pano‐matching achieves state of‐the‐art performances on feature matching and relative pose estimation among source code available methods.

Computing Epipolar Geometry from Unsynchronized Cameras
IEICE Transactions on Information and Systems, 2007 Recently, many application systems have been developed by using a large number of cameras. If 3D points are observed from synchronized cameras, the multiple view geometry of these cameras can be computed and the 3D reconstruction of the scene is available. Thus, the synchronization of multiple cameras is essential.

A case against epipolar geometry
, 1994 We discuss briefly a number of areas where epipolar geometry is currently central in carrying out visual tasks. In contrast we demonstrate configurations for which 3D projective invariants can be computed from perspective stereo pairs, but epipolar geometry (and full projective structure) cannot.

Learning epipolar geometry from image sequences
2003 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2003. Proceedings., 2003 We wish to determine the epipolar geometry of a stereo camera pair from image measurements alone. This paper describes a solution to this problem, which does not require a parametric model of the camera system, and consequently applies equally well to a wide class of stereo configurations.

Visual SLAM based on semantic information and geometric constraints in dynamic environment
智能科学与技术学报, 2023 Most existing visual SLAM systems assume that the external environment is static, ignoring the influence of dynamic objects on the SLAM system. This assumption largely affects the accuracy and robustness of autonomous navigation. To address this issue, a

Learning to Synthesize a 4D RGBD Light Field from a Single Image
, 2017 We present a machine learning algorithm that takes as input a 2D RGB image and synthesizes a 4D RGBD light field (color and depth of the scene in each ray direction).

ShapeFit and ShapeKick for Robust, Scalable Structure from Motion
, 2016 We introduce a new method for location recovery from pair-wise directions that leverages an efficient convex program that comes with exact recovery guarantees, even in the presence of adversarial outliers.

Propagation of an Earth-directed coronal mass ejection in three dimensions
, 2010 Solar coronal mass ejections (CMEs) are the most significant drivers of adverse space weather at Earth, but the physics governing their propagation through the heliosphere is not well understood.

What Epipolar Geometry Can Do for Video-Surveillance [PDF]
, 2013 In this paper we deal with the problem of matching moving objects between multiple views using geometrical constraints. We consider systems of still, uncalibrated and partially overlapped cameras and design a method able to automatically learn the epipolar geometry of the scene.
