Graph embedding via multi-scale graph representations

Information Sciences, 2021
Abstract Graph embedding provides an effective way to encode graph nodes as continuous vector representations in a low-dimensional space. The high-order proximities based graph embedding methods can preserve global structures, but the high-order proximities based objectives typically imply non-convex optimization and high computational ...

Shape Indexing by Multi-scale Representation

Image and Vision Computing, 1998
Accessing large image databases requires effective indexing in order to restrict the number of database items that have to be processed. Indexing based on shapes is particularly challenging owing to the difficulty of deriving a similarity measure that supports clustering of shapes conforming with human perceptual similarity.

Multi-scale representation of tribological surfaces

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2002
Many numerical surface topography analysis methods exist today. However, even for the moderately complicated topography of a tribological surface these methods can provide only limited information. The reason is that tribological surfaces often exhibit a non-stationary and multi-scale nature while the numerical methods currently used work well with ...

Multi-Scale Representation of a Digital Line

Cartography and Geographic Information Systems, 1996
A scheme for multi-scale geometrical representation of a digital line is proposed. A digital line is represented as a structured object in which lines at different levels of resolution are represented as lists, quadcodes are used as control mechanism for guiding line simplification at multiple scales of a pyramid, and operators for simplification and ...

A Seamless Representation of Multi-scale Clouds

2009 Fifth International Joint Conference on INC, IMS and IDC, 2009
In digital earth based virtual environments representation of clouds from earth scale to small regional scale is characteristic but not addressed yet. Our methods integrate clouds of different scales and achieve seamless switch between them when view position changes. The paper uses an interactive physical based method to calculate density distribution
