FPGA IMPLEMENTATION OF ROAD NETWORK EXTRACTION USING MORPHOLOGICAL OPERATOR

open access: yesImage Analysis and Stereology, 2016
In the remote sensing analysis, automatic extraction of road network from satellite or aerial images is the most needed approach for efficient road database creation, refinement, and updating. Mathematical morphology is a tool for extracting the features

Connected components of the strata of the moduli spaces of quadratic differentials [PDF]

open access: yes, 2007
In two fundamental classical papers, Masur and Veech have independently proved that the Teichmueller geodesic flow acts ergodically on each connected component of each stratum of the moduli space of quadratic differentials. It is therefore interesting to

A Dynamic Network Model For Population Growth And Urbanization

open access: yesCumhuriyet Science Journal, 2019
Dynamic networks imply those states of which change over time and suchchanges are generally associated with the topology of a network. Dynamic modelsare currently needed for numerous systems which could be defined as a networkmodel.

Research on the Control Method of the PV Grid-Connected Inverter under an Asymmetrical Power Grid Fault

open access: yesEnergies, 2023
The negative-sequence current component and harmonic components generated when an asymmetrical fault occurs in the power grid seriously affect the normal operation of the photovoltaic (PV) grid-connected inverter.

A morphological approach for segmentation and tracking of human faces [PDF]

open access: yes, 2000
A new technique for segmenting and tracking human faces in video sequences is presented. The technique relies on morphological tools such as using connected operators to extract the connected component that more likely belongs to a face, and partition ...

Giant strongly connected component of directed networks

open access: yes, 2001
We describe how to calculate the sizes of all giant connected components of a directed graph, including the {\em strongly} connected one. Just to the class of directed networks, in particular, belongs the World Wide Web.
