Preserving properties of object shape by computations in primary visual cortex [PDF]

open access: yesProceedings of the National Academy of Sciences, 2004
Although our visual system is extremely good at extracting objects from the visual scene, this process involves complicated computations that are thought to require image processing by many successive cortical areas. Thus, intermediate stages in object extraction should not eliminate essential properties of the objects that are still required by later ...

Bases for shape preserving curves

open access: yesJournal of Numerical Analysis and Approximation Theory, 2003
The shape preserving properties of a curve in \(\mathbb{R}^2\) depend on the properties of the function basis we use in its representation. Both sign consistent and totally positive bases have shape preserving properties useful in Computer Aided ...

Bernstein operators of second kind and blending systems

open access: yesJournal of Numerical Analysis and Approximation Theory, 2017
We consider the fundamental polynomials associated with the Bernstein operators of second kind. They form a blending system for which we study some shape preserving properties. Modified operators are introduced; they have better interpolation properties.

A Family of 6-Point n-Ary Interpolating Subdivision Schemes

open access: yesMehran University Research Journal of Engineering and Technology, 2018
We derive three-step algorithm based on divided difference to generate a class of 6-point n-ary interpolating sub-division schemes. In this technique second order divided differences have been calculated at specific position and used to insert new ...

On the construction of shape preserving taper curves.

open access: yesSilva Fennica, 1993
There exists an algorithm for construction interpolating quadratic splines which preserves the monotony of the data. The taper curves formed with this algorithm, QO-splines, have many good qualities when a sufficient number of measured diameters of a ...

Binary Darboux transformation and interactions of solitons for a higher-order matrix nonlinear Schrödinger equation

open access: yesResults in Physics, 2023
In this paper, we present two- and three-soliton solutions for a higher-order matrix nonlinear Schrödinger equation based on the binary Darboux transform constructed, and analyze various types of interaction properties of solitons.

Generalized Convexity Properties and Shape-Based Approximation in Networks Reliability

open access: yesMathematics, 2021
Some properties of generalized convexity for sets and functions are identified in case of the reliability polynomials of two dual minimal networks. A method of approximating the reliability polynomials of two dual minimal network is developed based on ...

Determination of an appropriate projection system for forest areas in Turkey

open access: yesGeodesy and Cartography, 2020
Geometrical surfaces such as sphere and ellipsoid are considered as reference surfaces since there is no geometric shape that perfectly represents the earth when translating the earth into a map plane.

Covariant Functors and Shapes in the Category of Compacts

open access: yesСовременная математика: Фундаментальные направления, 2019
In this paper, we consider covariant functors F : Comp → Comp acting in category of shape-preserving compact sets [2], infinite compact sets, and shape equivalence [9].
