This paper describes a vision-based, large-area, simultaneous localization and mapping (SLAM) algorithm that respects the low-overlap imagery constraints typical of underwater vehicles while exploiting the inertial sensor information that is routinely available on such platforms. We present a novel strategy for efficiently accessing and maintaining consistent covariance bounds within a SLAM inf...

The boundary chiral ring of a 2d gauged linear sigma model on a Kähler manifold X classifies the topological D-brane sectors and the massless open strings between them. While it is determined at small volume by simple group theory, its continuation to generic volume provides highly non-trivial information about the D-branes on X , related to the derived category D(X). We use this correspondence...

Normalized cross correlation (NCC), Sum of squared differences (SSD), and Sum of absolute differences (SAD) are the linear correlation measures generally used for stereo correspondence. These measures fail to establish the correspondence under nonideal conditions such as specular reflection, occlusion etc. In this paper, the similarity measures for stereo correspondence based on rank correlatio...

Let G be Sp(2n, F) (resp. SO(2n + 1, F)), where F is a p-adic field of characteristic zero. In this paper, we give a correspondence which associates to an irreducible representation of G an m-tuple of irreducible representations of lower rank symplectic (resp. orthogonal) groups based on the supercuspidal support of . We show that this correspondence respects the induction and Jacquet module fu...

a fully fuzzy linear programming (fflp) formulation for the reservoir operation of amultipurpose reservoir in presented in the ongoing paper. in the real world, water resourcessystems usually have complexities among social, economic, natural resources andenvironmental aspects, which lead to multi-objective problems of significant uncertainties insystem parameters, objectives and in their intera...

[English]: This study aims to identify elementary students’ functional thinking in solving context-based linear pattern problems. It involved 65 fifth-grade students who had not learned generalizing patterns topic. Data was collected through tests and interviews. Students with correct answers on the test were grouped into three categories based types of use representations. Interviews conducted...

An unsupervised iterative N-dimensional point-set registration algorithm for unlabeled data (i.e., the correspondence between points is unknown) based on linear least squares proposed. The considers all possible point pairings and iteratively aligns two sets until number of pairs does not exceed maximum allowable one-to-one pairings.

Shape correspondence is the foundation for accurate statistical shape analysis; this is usually accomplished by identifying a set of sparsely sampled and well-corresponded landmark points across a population of shape instances. However, most available shape correspondence methods can only effectively deal with complete-shape correspondence, where a one-to-one mapping is assumed between any two ...

The project is concerned with the development of algorithms for the creation of photo-realistic 3D virtual environments, overcoming problems in mosaicing, colour and lighting changes, correspondence search speed and correspondence errors due to lack of surface texture. A number of related new algorithms have been investigated for image stitching, content based colour correction and efficient 3D...
