Fusing MPEG-7 visual descriptors for image classification [PDF]

open access: yes, 2005
This paper proposes three content-based image classification techniques based on fusing various low-level MPEG-7 visual descriptors. Fusion is necessary as descriptors would be otherwise incompatible and inappropriate to directly include e.g.

Compact Hash Codes for Efficient Visual Descriptors Retrieval in Large Scale Databases [PDF]

open access: yes, 2016
In this paper we present an efficient method for visual descriptors retrieval based on compact hash codes computed using a multiple k-means assignment. The method has been applied to the problem of approximate nearest neighbor (ANN) search of local and ...

Application of machine learning in MOFs for gas adsorption and separation

open access: yesMaterials Research Express, 2023
Metal–organic frameworks (MOFs) with high specific surface area, permanent porosity and extreme modifiability had great potential for gas storage and separation applications. Considering the theoretically nearly infinite variety of MOFs, it was difficult

Anisotropic Diffusion Descriptors

open access: yesComputer Graphics Forum, 2016
AbstractSpectral methods have recently gained popularity in many domains of computer graphics and geometry processing, especially shape processing, computation of shape descriptors, distances, and correspondence. Spectral geometric structures are intrinsic and thus invariant to isometric deformations, are efficiently computed, and can be constructed on

Prediction of inhibition constants of (R)-3-amidinophenylalanine inhibitors toward factor Xa by 2D-QSAR model

open access: yesVietnam Journal of Science, Technology and Engineering, 2022
A coagulation cascade forms through proteolytic reactions and involves different factors. There are two coagulation pathways, including intrinsic and extrinsic mechanisms, which converge by the formation of factor Xa.
