A Deep Learning-Based Hyperspectral Keypoint Representation Method and Its Application for 3D Reconstruction

open access: yesIEEE Access, 2022
In previous studies, the keypoints and their feature descriptors of a hyperspectral image have not received enough attention. Compared with RGB images, the rich feature information of a hyperspectral image can not only constrain the spatial positions of ...

Universal‐Descriptors‐Guided Design of Single Atom Catalysts toward Oxidation of Li2S in Lithium–Sulfur Batteries

open access: yesAdvanced Science, 2021
The sulfur redox kinetics critically matters to superior lithium–sulfur (Li–S) batteries, for which single atom catalysts (SACs) take effect on promoting Li2S redox process and mitigating the shuttle behavior of lithium polysulfide (LiPs).

Analysis of Application of Cluster Descriptions in Space of Characteristic Image Features

open access: yesData, 2018
In this paper, we propose an investigation of the properties of structural image recognition methods in the cluster space of characteristic features. Recognition, which is based on key point descriptors like SIFT (Scale-invariant Feature Transform), SURF

On improving Kaiwa (会話) assessment: Incorporating JF Standard descriptors and MFRM

open access: yesIndonesian Journal of Applied Linguistics, 2023
Despite the available rubrics, assessing speaking objectively has been a debatable issue to language assessment experts mostly due to the dependence on the raters’ authority. Scoring speaking performance often results in unfairness since subjectivity may
