Discrete line fields on surfaces [PDF]
Topology and Its Applications, 2021 Vector fields and line fields, their counterparts without orientations on tangent lines, are familiar objects in the theory of dynamical systems. Among the techniques used in their study, the Morse--Smale decomposition of a (generic) field plays a fundamental role, relating the geometric structure of phase space to a combinatorial object consisting of ...

Discrete time model of self-oscillations with spectral line widening
Физика волновых процессов и радиотехнические системы, 2022 An algorithm for generating quasi-harmonic self-oscillations with a uniformly widened spectral line is presented. The algorithm is based on the equation of motion of the Thomson-type DT-oscillator, which introduced a random effect in the form of band ...

Discrete Representation of Straight Lines [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1984 If a continuous straight line segment is digitized on a regular grid, obviously a loss of information occurs. As a result, the discrete representation obtained (e.g., a chaincode string) can be coded more conveniently than the continuous line segment, but measurements of properties (such as line length) performed on the representation have an intrinsic

Discrete Line Congruences for Shading and Lighting [PDF]
Computer Graphics Forum, 2013 AbstractTwo‐parameter families of straight lines (line congruences) are implicitly present in graphics and geometry processing in several important ways including lighting and shape analysis. In this paper we make them accessible to optimization and geometric computing, by introducing a general discrete version of congruences based on piecewise‐linear ...
