Equivalence, Partial Order and Lattice of Neighborhood Sequences on the Triangular Grid

open access: yesMathematics, 2022
In (digital) grids, neighbor relation is a crucial concept; digital distances are based on paths through neighbor points. Digital distances are significant, e.g., in digital image processing for giving an approximation of the Euclidean distance and ...

Dilation and Erosion on the Triangular Tessellation: An Independent Approach

open access: yesIEEE Access, 2018
In this paper, a new idea for morphological operations, i.e., dilation and erosion on the regular triangular tessellation is presented. The triangles have two orientations; they are addressed by zero-sum and one-sum triplets and called even and odd ...

Bijective, Non-Bijective and Semi-Bijective Translations on the Triangular Plane

open access: yesMathematics, 2019
The triangular plane is the plane which is tiled by the regular triangular tessellation. The underlying discrete structure, the triangular grid, is not a point lattice. There are two types of triangle pixels. Their midpoints are assigned to them.

A Reliable Localization Algorithm Based on Grid Coding and Multi-Layer Perceptron

open access: yesIEEE Access, 2020
The traditional RSS-based fingerprint localization algorithm needs RSS values from all access points (AP) at each reference point (RP). In the large-scale indoor environment, the increasing of the number of APs will lead to establish a large-scale ...
