Estimating Intrinsic Camera Parameters from the Fundamental Matrix Using an Evolutionary Approach
EURASIP Journal on Advances in Signal Processing, 2004 Calibration is the process of computing the intrinsic (internal) camera parameters from a series of images. Normally calibration is done by placing predefined targets in the scene or by having special camera motions, such as rotations.

Singular Vector Methods for Fundamental Matrix Computation [PDF]
, 2013 International audienceThe normalized eight-point algorithm is broadly used for the computation of the fundamental matrix between two images given a set of correspondences. However, it performs poorly for low-size datasets due to the way in which the rank-

Clustering Assisted Fundamental Matrix Estimation
Computer Science & Information Technology ( CS & IT ), 2015 In computer vision, the estimation of the fundamental matrix is a basic problem that has been extensively studied. The accuracy of the estimation imposes a significant influence on subsequent tasks such as the camera trajectory determination and 3D reconstruction. In this paper we propose a new method for fundamental matrix estimation that makes use of

A high-accuracy algorithm for computing fundamental matrix
, 2004 This paper analyses the different influence on the Fundamental Matrix (F Matrix) by the different matched points in images and the weighted factor is introduced to express the distance between the matched point and the epipolar line which has the obvious

Metastatic niche shaped by host factors influences disseminated cancer cell fate
FEBS Letters, EarlyView.Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Lysyl oxidase (LOX)‐mediated remodeling of the extracellular matrix
FEBS Letters, EarlyView.The lysyl oxidase (LOX) family of enzymes drives extracellular matrix remodeling by oxidizing collagen, elastin, and fibronectin, promoting covalent cross‐link formation. This activity regulates tissue architecture and mechanical properties, while its dysregulation contributes to fibrosis, cardiovascular disease, glaucoma, connective tissue disorders ...

Generalization of a fundamental matrix
Linear Algebra and its Applications, 1981 AbstractIt is shown that, for a finite ergodic Markov chain, basic descriptive quantities, such as the stationary vector and mean first-passage matrix, may be calculated using any one of a class of fundamental matrices. New applications of the use of these operators are discussed.
