Multi-scale space-variant FRep cellular structures [PDF]

open access: yes, 2013
Existing mesh and voxel based modeling methods encounter difficulties when dealing with objects containing cellular structures on several scale levels and varying their parameters in space.

An Objective Fabric Smoothness Assessment Method Based on a Multi-Scale Spatial Masking Model

open access: yesIEEE Access, 2019
Fabric smoothness appearance assessment plays an important role in the textile and apparel industry. It remains a challenging task to evaluate the fabric smoothness objectively.

Modulation spaces with scaling symmetry

open access: yesApplied and Computational Harmonic Analysis, 2020
We indicate how to construct a family of modulation function spaces that have a scaling symmetry. We also illustrate the behavior of the Schr\"odinger multiplier on such function spaces.

Global Distribution of Persistence of Total Electron Content Anomaly

open access: yesAtmosphere, 2019
To better understand the ionospheric morphology response to lithospheric activities, we study the global location preference of the positive and negative total electron content (TEC) anomalies persisting continuously for longer than 24 h at middle and ...

A parameterless scale-space approach to find meaningful modes in histograms - Application to image and spectrum segmentation [PDF]

open access: yesInt. J. Wavelets Multiresolution Inf. Process., 2014
In this paper, we present an algorithm to automatically detect meaningful modes in a histogram. The proposed method is based on the behavior of local minima in a scale-space representation.

Scale-space and edge detection using anisotropic diffusion [PDF]

open access: yes, 1990
The scale-space technique introduced by Witkin involves generating coarser resolution images by convolving the original image with a Gaussian kernel.

Considerations and Framework for Foveated Imaging Systems †

open access: yesPhotonics, 2018
Foveated sight as observed in some raptor eyes is a motivation for artificial imaging systems requiring both wide fields of view as well as specific embedded regions of higher resolution.

Scaling context space [PDF]

open access: yesProceedings of the 40th Annual Meeting on Association for Computational Linguistics - ACL '02, 2001
Context is used in many NLP systems as an indicator of a term's syntactic and semantic function. The accuracy of the system is dependent on the quality and quantity of contextual information available to describe each term. However, the quantity variable is no longer fixed by limited corpus resources.

Patch-NetVLAD: Multi-Scale Fusion of Locally-Global Descriptors for Place Recognition [PDF]

open access: yesComputer Vision and Pattern Recognition, 2021
Visual Place Recognition is a challenging task for robotics and autonomous systems, which must deal with the twin problems of appearance and viewpoint change in an always changing world.

Partial Block Scheme and Adaptive Update Model for Kernelized Correlation Filters-Based Object Tracking

open access: yesApplied Sciences, 2018
In visual object tracking, the dynamic environment is a challenging issue. Partial occlusion and scale variation are typical challenging problems. We present a correlation-based object tracking based on the discriminative model.
