Projective rectification from the fundamental matrix [PDF]

open access: yesImage and Vision Computing, 2005
This paper describes a direct, self-contained method for planar image rectification of stereo pairs. The method is based solely on an examination of the Fundamental matrix, where an improved method is given for the derivation of two projective ...

Similarity relations and exponential of dual-generalized complex matrices

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023
In this study, taking into account the fundamental properties of dual-generalized complex (DGC) matrices, various types of similarity relations are introduced considering coneigenvalues/coneigenvectors via di erent conjugates.

Boundedness and stability in nonlinear systems of differential equations using a modified variation of parameters formula

open access: yesCubo, 2023
In this research we introduce a new variation of parameters for systems of linear and nonlinear ordinary differential equations. We use known mathematical methods and techniques including Gronwall’s inequality and fixed point theory to obtain boundedness

A Novel Error Criterion of Fundamental Matrix Based on Principal Component Analysis

open access: yesRemote Sensing, 2022
Estimating the fundamental matrix (FM) using the known corresponding points is a key step for three-dimensional (3D) scene reconstruction, and its uncertainty directly affects camera calibration and point-cloud calculation.

Fundamental Matrix Computing Based on 3D Metrical Distance

open access: yesAlgorithms, 2021
To reconstruct point geometry from multiple images, computation of the fundamental matrix is always necessary. With a new optimization criterion, i.e., the re-projective 3D metric geometric distance rather than projective space under RANSAC (Random ...

Fundamental Strings and D-strings in the IIB Matrix Model [PDF]

open access: yes, 1997
The matrix model for IIB Superstring proposed by Ishibashi, Kawai, Kitazawa and Tsuchiya is investigated. Consideration of planar and non-planar diagrams suggests that the large N perturbative expansion is consistent with the double scaling limit ...

Note on Matrix Model with Massless Flavors [PDF]

open access: yes, 2002
In this note, following the work of Seiberg in hep-th/0211234 for the conjecture between the field theory and matrix model in the case with massive fundamental flavors, we generalize it to the case with massless fundamental flavors.

Adding Fundamental Matter to ``Chiral Rings and Anomalies in Supersymmetric Gauge Theory'' [PDF]

open access: yes, 2002
We consider a supersymmetric U(N) gauge theory with matter fields in the adjoint, fundamental and anti-fundamental representations. As in the framework which was put forward by Dijkgraaf and Vafa, this theory can be described by a matrix model.

Calibration Method Based on the Image of the Absolute Quadratic Curve

open access: yesIEEE Access, 2019
In this paper, a new camera calibration method based on the image of the absolute quadratic curve (IAC) is proposed, and a new target is designed for this method, which is both convenient and flexible.
