Algorithms for Mobile Robot Localization and Mapping, Incorporating Detailed Noise Modeling and Multi-scale Feature Extraction [PDF]

open access: yes, 2006
Mobile robot localization and mapping in unknown environments is a fundamental requirement for effective autonomous navigation. Three different approaches to localization and mapping are presented.

Details of our multi-scale spatial focus features enhancement strategy.

open access: yes, 2022
The input of the module is the output of the last convolutional layer. First, a soft attention mechanism with SPP is used to obtain the multi-scale spatial features.

Double Attention for Multi-Label Image Classification

open access: yesIEEE Access, 2020
Multi-label image classification is an essential task in image processing. How to improve the correlation between labels by learning multi-scale features from images is a very challenging problem.

Direct numerical simulation of complex viscoelastic flows via fast lattice-Boltzmann solution of the Fokker–Planck equation [PDF]

open access: yes, 2013
Micro–macro simulations of polymeric solutions rely on the coupling between macroscopic conservation equations for the fluid flow and stochastic differential equations for kinetic viscoelastic models at the microscopic scale.

Efficient Lightweight Attention Network for Face Recognition

open access: yesIEEE Access, 2022
Although face recognition has achieved great success due to deep learning, many factors may affect the quality of faces in the wild, such as pose changes, age variations, and light changes, which can seriously affect the performance of face recognition ...

Robust Multi-scale Extraction of Blob Features [PDF]

open access: yes, 2003
This paper presents a method for detection of homogeneous regions in grey-scale images, representing them as blobs. In order to be fast, and not to favour one scale over others, the method uses a scale pyramid. In contrast to most multi-scale methods this one is non-linear, since it employs robust estimation rather than averaging to move through scale ...

Multi‐scale Feature Extraction on Point‐Sampled Surfaces [PDF]

open access: yesComputer Graphics Forum, 2003
Abstract We present a new technique for extracting line‐type features on point‐sampled geometry. Given an unstructuredpoint cloud as input, our method first applies principal component analysis on local neighborhoods toclassify points according to the likelihood that they belong to a feature.

Disparity Using Feature Points in Multi Scale [PDF]

open access: yes, 2002
In this paper we describe a statistical framework for binocular disparity estimation. We use a bank of Gabor filters to compute multiscale phase signatures at detected feature points. Using a von Mises distribution,w e calculate correspondence probabilities for the feature points in different images using the phase differences at different scales.

Shape Matching Based on Multi-Scale Invariant Features

open access: yesIEEE Access, 2019
Shape matching has been extensively used in various fields. The local feature-based or global feature-based algorithms can hardly describe the shape comprehensively due to their inherent defects.
