Matching Through Features and Features Through Matching

open access: yes, 2012
This paper addresses how to construct features for the problem of image correspondence, in particular, the paper addresses how to construct features so as to maintain the right level of invariance versus discriminability. We show that without additional prior knowledge of the 3D scene, the right tradeoff cannot be established in a pre-processing step ...

Guided Local Feature Matching with Transformer

open access: yesRemote Sensing, 2023
GLFNet is proposed to be utilized for the detection and matching of local features among remote-sensing images, with existing sparse feature points being leveraged as guided points.

Convolutional neural network architecture for geometric matching [PDF]

open access: yes, 2017
We address the problem of determining correspondences between two images in agreement with a geometric model such as an affine or thin-plate spline transformation, and estimating its parameters. The contributions of this work are three-fold.

Reliable features matching for humanoid robots [PDF]

open access: yes2007 7th IEEE-RAS International Conference on Humanoid Robots, 2007
This paper describes a visual feature detector and descriptor scheme designed to address the specific problems of humanoid robots in the tasks of visual odometry, localization, and SLAM (Simultaneous Localization And Mapping). During walking, turning, and squatting movements, the camera of a humanoid robot moves in jerky and sometimes unpredictable way.

A hierarchical genetic disparity estimation algorithm for multiview image synthesis [PDF]

open access: yes, 2000
A hierarchical genetic algorithm for disparity estimation is presented. The goal, to estimate reliable disparity fields with low computational cost, is reached using a hierarchical genetic matching procedure.

Robust Matching of Aerial-Ground Images Optimized by Multi-Layer Progressive Feature Alignment Network [PDF]

open access: yesJisuanji gongcheng, 2023
Fine 3D models provide the key spatial basic information for smart city construction. However, factors such as perspective changes and occlusion lead to inaccurate edges, holes, and blurry building facade textures in 3D models generated from aerial ...

RESEARCH PROGRESS ON FEATURE MATCHING OF SAR AND OPTICAL IMAGES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Before obtaining information and identifying ground target from images, image matching is necessary. However, problems of strong pixel noise interference and nonlinear gray scale differences in synthetic aperture radar image still exist. Feature matching

An improved spatiogram similarity measure for robust object localisation [PDF]

open access: yes, 2007
Spatiograms were introduced as a generalisation of the commonly used histogram, providing the flexibility of adding spatial context information to the feature distribution information of a histogram.
