Local Refinement for Stereo Regularization [PDF]
2014 22nd International Conference on Pattern Recognition, 2014 Stereo matching is an inherently difficult problem due to ambiguous and noisy texture. The non-convexity and non-differentiability makes local linear (or quadratic) approximations poor, thereby preventing the use of standard local descent methods. Therefore recent methods are predominantly based on discretization and/or random sampling of some class of

Algorithms, 2022 In analysis of problems with parametric spline boundaries that are immersed or inserted into an underlying domain, the discretization on the underlying domain usually does not conform to the inserted boundaries.

Local alignment refinement using structural assessment. [PDF]
PLoS ONE, 2008 Homology modeling is the most commonly used technique to build a three-dimensional model for a protein sequence. It heavily relies on the quality of the sequence alignment between the protein to model and related proteins with a known three dimensional ...

Cartesian Mesh Generation with Local Refinement for Immersed Boundary Approaches
Journal of Marine Science and Engineering, 2021 In this paper, an efficient and robust Cartesian Mesh Generation with Local Refinement for an Immersed Boundary Approach is proposed, whose key feature is the capability of high Reynolds number simulations by the use of wall function models, bypassing ...

Localized Delaunay Refinement for Volumes [PDF]
Computer Graphics Forum, 2011 AbstractDelaunay refinement, recognized as a versatile tool for meshing a variety of geometries, has the deficiency that it does not scale well with increasing mesh size. The bottleneck can be traced down to the memory usage of 3D Delaunay triangulations.

Locally refinable parametric snakes [PDF]
2015 IEEE International Conference on Image Processing (ICIP), 2015 Shape segmentation is an active field of research in biomedical imaging. In this context, we present a new parameterization of a snake that is locally refinable. We introduce the possibility of locally increasing the approximation power of the parametric model by inserting basis functions at a specific location.

Exact local refinement using Fourier interpolation for nonuniform-grid modeling
Earth and Planetary Physics, 2017 Numerical solver using a uniform grid is popular due to its simplicity and low computational cost, but would be unfeasible in the presence of tiny structures in large-scale media.

Local Abstraction-Refinement for the mu-Calculus [PDF]
International Journal on Software Tools for Technology Transfer, 2007 A key technique for the verification of programs is counterexample-guided abstraction–refinement (CEGAR). Grumberg et al. (LNCS, vol 3385, pp. 233–249. Springer, Berlin, 2005; Inf Comput 205(8):1130–1148, 2007) developed a CEGAR-based algorithm for the modal μ-calculus. There, every abstract state is split in a refinement step.

De-Skewing LiDAR Scan for Refinement of Local Mapping
Sensors, 2020 Simultaneous localization and mapping have become a basic requirement for most automatic moving robots. However, the LiDAR scan suffers from skewing caused by high-acceleration motion that reduces the precision in the latter mapping or classification ...
