Match or No Match: Keypoint Filtering based on Matching Probability

2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2020
Keypoints that do not meet the needs of a given application are a very common accuracy and efficiency bottleneck in many computer vision tasks, including keypoint matching and 3D reconstruction. Many computer vision and machine learning methods have dealt with this issue, trying to improve keypoint detection or the matching process.

Stacked Cross Attention for Image-Text Matching

European Conference on Computer Vision, 2018
In this paper, we study the problem of image-text matching. Inferring the latent semantic alignment between objects or other salient stuffs (e.g. snow, sky, lawn) and the corresponding words in sentences allows to capture fine-grained interplay between ...

Matching NLO QCD computations with Parton Shower simulations: the POWHEG method

, 2007
The aim of this work is to describe in detail the POWHEG method, first suggested by one of the authors, for interfacing parton-shower generators with NLO QCD computations.

Causal Inference without Balance Checking: Coarsened Exact Matching

Political Analysis, 2012
We discuss a method for improving causal inferences called “Coarsened Exact Matching” (CEM), and the new “Monotonic Imbalance Bounding” (MIB) class of matching methods from which CEM is derived.

Matchings and Perfect Matchings

2009
As a young branch of mathematics, Graph Theory has experienced the explosion growth as the same phenomenon that has been taking place in computing science and communication networking. In the mean time, there are many new terminologies and knowledge accumulated in the process. So there are often more than one names or notions defined for a same entity.

Matching properties of MOS transistors

European Solid-State Circuits Conference, 1988
The matching properties of the threshold voltage, substrate factor and current factor of MOS transistors have been analysed and measured. Improvements of the existing theory are given, as well as extensions for long distance matching and rotation of ...

Job Matching and the Theory of Turnover

Journal of Political Economy, 1979
A long-run equilibrium theory of turnover is presented and is shown to explain the important regularities that have been observed by empirical investigators.

Matching

Preventive Medicine, 1995
Matching is an intuitively appealing design strategy for ensuring balance on one or more potential confounding variables, usually either among subjects who were exposed or unexposed to a suspected risk factor for disease in a cohort study or between diseased and nondiseased subjects in a case-control study.

Match effects [PDF]

Research in Economics, 2008
We present an empirical model of earnings that controls for observable and unobservable characteristics of workers (person effects), unmeasured characteristics of their employers (firm effects), and unmeasured characteristics of worker-firm matches (match effects). We interpret these as the returns to general human capital, firm-specific human capital,
