Dual Dominant Local Binary Descriptor for Face Recognition
Proceedings of the 2019 3rd International Conference on Innovation in Artificial Intelligence, 2019Recent years, many LBP variants tried to improve its discrimination and robustness, however, brought about extra cost. In this paper, we propose a compact yet highly robust local binary descriptor Dual Dominate Patterns (DDP) for face recognition which focuses on horizontal, vertical and inclined 45-degree orientations.

Local Feature Descriptor Learning with a Dual Hard Sampling Strategy
2019 IEEE International Symposium on Multimedia (ISM), 2019Local feature descriptor learning based on Convolutional Neural Network (CNN) has demonstrated its capability to generate descriptors with high quality. While extensive studies focused on mining hard non-matching examples to improve descriptor learning performance, a random sampling strategy is adopted for matching examples.

A Ground-State Dual-Descriptor Strategy for Screening Efficient Singlet Fission Systems
The Journal of Physical Chemistry Letters, 2023Exploration of singlet fission (SF) materials is vital for enhancing the photoelectric conversion efficiency of photovoltaic devices, and the development of an effective screening means is in great demand. In this work, we for the first time propose a promising dual-descriptor strategy to predict the SF energetics (ΔESF) from ground-state electronic ...

Descriptors of Pain Sensation: A Dual Hierarchical Model of Latent Structure
The Journal of Pain, 2012Recently, the lexicon of pain was refined into a parsimonious set of words making up the Pain Descriptor System (PDS). The present study investigated the latent structure of the sensory category of the PDS with its 24 descriptors distributed equally across 8 subcategories.

Cerebral Microbleed Detection Via Fourier Descriptor with Dual Domain Distribution Modeling
2020 IEEE 17th International Symposium on Biomedical Imaging Workshops (ISBI Workshops), 2020In this study we propose a novel cerebral microbleed (CMB) detection technique which simultaneously utilizes distribution information in dual domains and shape information obtained by a Fourier descriptor, and does not rely on a large set of training data.

A Compact Binary Aggregated Descriptor via Dual Selection for Visual Search
Proceedings of the 24th ACM international conference on Multimedia, 2016To achieve high retrieval accuracy over a large scale image/video dataset, recent research efforts have demonstrated that employing extremely high-dimensional descriptors such as the Fisher Vector (FV) and the Vector of Locally Aggregated Descriptors (VLAD) can yield good performance.

Exploring Dual-Polarimetic Descriptors for Sentinel-L Based Ship Detection
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018This study addresses the use of dual-polarimetric descriptors for ship detection and characterization from Synthetic Aperture Radar (SAR) data. Ship detection is usually performed independently on each polarization channel and the results are merged subsequently.

Abstract Nucleophilicity and elecrophilicity of mono and disubstituted silylenes are analyzed using the molecular electrostatic potential and the dual descriptor Δ f ( r → ) , defined within the so called conceptual DFT. A set of 32 compounds has been chosen which can be classified into 4 groups or families based on a linear ...
