The Eighty Six H alpha Spectra from the Orion Nebula (M42, Sh2-281) with DEFPOS
(INDIAN ACAD SCIENCES, 2017-11-27)
In this study, eighty six H alpha (6563 angstrom) emission line spectra from the central region (similar to 40' x 40') of the Orion Nebula (NGC1976, M42, Sh2-281) have been obtained using DEFPOS spectrometer with a circular ...
Mean-square deviation analysis of the zero-attracting variable step-size LMS algorithm
(SPRINGER LONDON LTD, 2017-03)
The well-known variable step-size least-mean-square (VSSLMS) algorithm provides faster convergence rate while maintaining lower mean-square error than the conventional LMS algorithm. The performance of the VSSLMS algorithm ...
Histogram-Based Feature Extraction from Individual Gray Matter Similarity-Matrix for Alzheimer's Disease Classification
(IOS PRESS, 2017)
Automatic computer-aided diagnosis (CAD) systems have been widely used in classification of patients who suffer from Alzheimer's disease (AD). This paper presents an automatic CAD system based on histogram feature extraction ...
Mimicking speaker's lip movement on a 3D head model using cosine function fitting
(POLSKA AKAD NAUK, 2017-10)
Real-time mimicking of human facial movement on a 3D head model is a challenge which has attracted attention of many researchers. In this research work we propose a new method for enhancing the capturing of the shape of ...
Statistical approach based iris recognition using local binary pattern
(FEDERACION ASOCIACIONES INGENIEROS INDUSTRIALES ESPANA, 2017-01)
Among biometric features utilized for identity recognition purposes, iris has proven to be the most reliable one in terms of sufficient distinctiveness, which has direct implications and importance towards improving the ...
(δ, 2)-Primary Ideals of a Commutative Ring
(Springer Science and Business Media Deutschland GmbH, December 2)
Let R be a commutative ring with nonzero identity, let I(R) be the set of all ideals of R and δ: I(R) → I(R) an expansion of ideals of R defined by I ↦ δ(I). We introduce the concept of (δ, 2)-primary ideals in commutative ...
Robust non-blind color video watermarking using QR decomposition and entropy analysis
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2016-07)
Issues such as content identification, document and image security, audience measurement, ownership and copyright among others can be settled by the use of digital watermarking. Many recent video watermarking methods show ...
H alpha line measurements from ten diffuse galactic sources using the DEFPOS facility
(WILEY-V C H VERLAG GMBH, 2015-07)
The hydrogen Balmer-alpha emission line spectrum of ten diffuse ionization sources in the Milk Way - NGC 40 (WC8), NGC 2022, NGC 6210, NGC 6618 (M17, Sh2-45), NGC 6720 (M57), NGC 6781, NGC 6888 (Sh2-105), NGC 6992 (Sh2-103), ...
From apparent to real age: Gender, age, ethnic, makeup, and expression bias analysis in real age estimation
(IEEE Computer Society, 2018-12-13)
Real age estimation in still images of faces is an active area of research in the computer vision community. However, very few works attempted to analyse the apparent age as perceived by observers. Apparent age estimation ...
Volumetric Histogram-Based Alzheimer's Disease Detection Using Support Vector Machine
(NLM (Medline), 2019)
In this research work, machine learning techniques are used to classify magnetic resonance imaging brain scans of people with Alzheimer's disease. This work deals with binary classification between Alzheimer's disease and ...
