Kählerian Information Geometry for Signal Processing [PDF]
Entropy, 2015 We prove the correspondence between the information geometry of a signal filter and a Kähler manifold. The information geometry of a minimum-phase linear system with a finite complex cepstrum norm is a Kähler manifold.

Sum-of-squares geometry processing [PDF]
ACM Transactions on Graphics, 2021 Geometry processing presents a variety of difficult numerical problems, each seeming to require its own tailored solution. This breadth is largely due to the expansive list of geometric primitives , e.g., splines, triangles, and hexahedra, joined with an ever-expanding variety of objectives ...

Geometry of Thermodynamic Processes [PDF]
Entropy, 2018 Since the 1970s, contact geometry has been recognized as an appropriate framework for the geometric formulation of thermodynamic systems, and in particular their state properties. More recently it has been shown how the symplectization of contact manifolds provides a new vantage point; enabling, among other things, to switch easily between the energy ...

Crack Detection and Geometry Measurements using Digital Image Processing
Diyala Journal of Engineering Sciences, 2021 Digital image processing (DIP), is the use of a digital computer to process digital images through an algorithm. In this work DIP used to perform crack/defect Detection and geometry measurements in terms of angle, length, and width by building a MATLAB ...

Perception of global facial geometry is modulated through experience [PDF]
PeerJ, 2015 Identification of personally familiar faces is highly efficient across various viewing conditions. While the presence of robust facial representations stored in memory is considered to aid this process, the mechanisms underlying invariant identification ...

Weighted Triangulations for Geometry Processing [PDF]
ACM Transactions on Graphics, 2014 In this article we investigate the use of weighted triangulations as discrete, augmented approximations of surfaces for digital geometry processing. By incorporating a scalar weight per mesh vertex, we introduce a new notion of discrete metric that defines an orthogonal dual structure for arbitrary triangle meshes and thus extends weighted Delaunay ...

Integer coordinates for intrinsic geometry processing [PDF]
ACM Transactions on Graphics, 2021 This paper describes a numerically robust data structure for encoding intrinsic triangulations of polyhedral surfaces. Many applications demand a correspondence between the intrinsic triangulation and the input surface, but existing data structures either rely on floating point values to encode correspondence, or do not support remeshing ...

An ultralight geometry processing library for parallel mesh refinement
Advances in Aerodynamics, 2022 In applications such as parallel mesh refinement, it remains a challenging issue to ensure the refined surface respects the original Computer-Aided Design (CAD) model accurately.

Geometry-aware direction field processing [PDF]
ACM Transactions on Graphics, 2009 Many algorithms in texture synthesis, nonphotorealistic rendering (hatching), or remeshing require to define the orientation of some features (texture, hatches, or edges) at each point of a surface. In early works, tangent vector (or tensor) fields were used to define the orientation of these features.
