Evolutionary agents for epipolar geometry estimation

2004 International Conference on Image Processing, 2004. ICIP '04., 2005
This paper presents an evolutionary agent-based approach to epipolar geometry estimation. Each agent stands for a minimum subset for computing fundamental matrix, and evolves autonomously in the vast solution space to get the optimal result. In so doing, the agents rely on some reactive behaviors such as reproduction and diffusion, and collaborate with

Analyzing Epipolar Geometry of 2-D Forward-Scan Sonar Stereo for Matching and 3-D Reconstruction

OCEANS 2018 MTS/IEEE Charleston, 2018
New generation of underwater 2-D forward-look sonar video systems operating at over 1 MHz frequency offer images with enhanced target detail. Within limited range of only tens of meters, they are the most suitable imaging systems for conducting visually ...

Asynchronous Event-Based Hebbian Epipolar Geometry

IEEE Transactions on Neural Networks, 2011
Epipolar geometry, the cornerstone of perspective stereo vision, has been studied extensively since the advent of computer vision. Establishing such a geometric constraint is of primary importance, as it allows the recovery of the 3-D structure of scenes.

Contour matching by epipolar geometry

SPIE Proceedings, 2003
Matching features computed in images is an important process in multiview image analysis. When the motion between two images is large, the matching problem becomes very difficult. In this paper, we propose a contour matching algorithm based on geometric constraints.

A novel linear technique to estimate the epipolar geometry

2001 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.01CH37221), 2002
The accurate reconstruction of the 3D scene structure from two different projections and the estimation of the camera scene geometry is of paramount importance in many computer vision tasks. Most of the information about the camera-scene geometry is encapsulated in the fundamental matrix. Estimating the fundamental matrix has been an object of research

Affine epipolar geometry via factorization method

Proceedings. Fourteenth International Conference on Pattern Recognition (Cat. No.98EX170), 2002
We present the intuitive interpretation of affine epipolar geometry for the orthographic, scaled orthographic, and paraperspective projection models in terms of the factorization method for the generalized affine projection (GAP) model proposed by Fujiki and Kurata (1997).

Camera Models and Epipolar Geometry

1996
In this chapter we present a detailed description of the epipolar geometry between two images taken by two different cameras or by a single camera at two different time instants. Since it is intimately related to camera models, we will start from modeling cameras, followed by several approximations to the full perspective projection.

NexusGS: Sparse View Synthesis with Epipolar Depth Priors in 3D Gaussian Splatting

Computer Vision and Pattern Recognition
Neural Radiance Field (NeRF) and 3D Gaussian Splatting (3DGS) have noticeably advanced photo-realistic novel view synthesis using images from densely spaced camera viewpoints.

Visual servoing based on epipolar geometry

Proceedings. 2000 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2000) (Cat. No.00CH37113), 2002
In this paper, we propose a new image-based approach using epipolar geometry. The problem which is addressed can be stated as follows: starting from a Cartesian situation, we want to drive the robot to a desired one using only image data provided during the robot motion. With regard to classical image-based visual servoing, we assume no prior knowledge

Epipolar geometry of opti-acoustic stereo imaging

Europe Oceans 2005, 2005
Optical and acoustic cameras are suitable imaging systems to inspect underwater structures, both in regular maintenance and security operations. Despite high resolution, optical systems have limited visibility range when deployed in turbid waters. In contrast, the new generation of high-frequency (MHz) acoustic cameras can provide images with enhanced ...
