MATRICES, VECTOR ALGEBRA, AND TRANSFORMATIONS PHILIP J. SCHNEIDER, DAVID H. EBERLY, in Geometric Tools for Computer Graphics, 2003 4.2 MATRIX REPRESENTATION OF POINTS AND VECTORS In Section 3.3.3, we showed that an affine frame F can be represented as a set of basis vectors and an origin F...
Repeating a gate sequence multiple times amplifies systematic errors coherently, making it a useful tool for characterizing quantum gates. However, the precision of such an approach is limited by low-frequency noise, while its efficiency is hindered by t
@param pointsMask optional Mat/Vector of 8u type representing the mask for the inliers as given by the @ref findHomography functionThis function is intended to filter the output of the decomposeHomographyMat based on additional information as described in @cite Malis2007 . The summary of the met...
In this respect, the same tools described for the PARAFAC model apply for Tucker-N models (cf. Section 2.22.2.1.3(iv)). The selection of the dimensionality vector and the optimal rotation is the most complex part of the validation process for these models, especially because, unlike PARAFAC...
Matrix-vector multiplication The methods for photonic matrix-vector multiplications (MVMs) mainly fall into three categories: the plane light conversion (PLC) method, Mach–Zehnder interferometer (MZI) method and wavelength division multiplexing (WDM) method. The detailed mechanism of these MVMs can be...

where θ i 𝜃𝑖 and Γ i 𝛤𝑖 are respectively the ( p − l i ) × 1 (𝑝−𝑙𝑖)×1 vector of free parameters and the p × ( p − l i ) 𝑝×(𝑝−𝑙𝑖) orthonormal basis of free parameters [32]. From Equation (20), we define Δ f i 𝛥𝑓𝑖...
Sea surface wind estimation plays an important role in many marine activities, such as navigation safety, performance, and marine exploration [1]. Accurate wind direction information is not only an important judgment factor for ship sailing direction, but also an important factor for military guidance...
For the operatorvector_to_essential_matrixa special configuration of scene points and cameras exists: if all 3D points lie in a single plane and additionally are all closer to one of the two cameras then the solution in the essential matrix is not unique but twofold. As a consequence both ...
