Research ArticleOpen accessEvery word in the titleVisible Derivative Spectroscopic Monitoring of the Old Woman Creek National Estuary During a Historically Dry Year and a Wet YearLorita Nivanthi Mihindukulasooriya, Brenna Shae Mabry, Madison Slocum, Joseph Daniel OrtizVisible derivative spectroscopy was used to interpret the sediment and phytoplankton assemblages within the old woman creek natural estuarine reserve during the summers of 2016 and 2017. A Varimax-rotated Principal Component Analysis (VPCA) of reflectance data collected from four sampling sites in 2016 identified three Varimax-rotated Principal Components (VPCs): Diatom + Illite (2016-VPC 1), Dinoflagellate Algae + Cyanobacteria + Cryptophytes … …American Journal of Environmental Sciences, Vol. 19, Issue 6 · 11 Jul 2024 · 4,669 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Visible and Near Infrared Polarized Lights on Spoofing Face DetectionAzim Zaliha Abd AzizFace spoofing countermeasure is vital to avoid an imposter from gaining access to security biometric systems by using face masks in various forms that mimic a valid user face. Recently, several studies have shown the ability of visible polarized light in distinguishing real and fake faces. In this paper, polarization imaging systems using visible and near infrared (NIR) are proposed … …Journal of Computer Science, Vol. 15, Issue 2 · 23 Feb 2019 · 7,893 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalytical Study of Signal-to-Noise Ratio for Visible Light Communication by Using Single SourceMohammad Syuhaimi Ab-Rahman, Nurain Izzati Shuhaimi, Luqman Al-Hakim Azizan, Mazen Radhe HassanProblem statement: In this study, optical wireless communication system using visible light is studied for indoor application. Approach: The process started with the calculation on performance of single source white LED where received power, channel DC gain and quality of data transmission (SNR computation) are identified. Through the simulation results, the SNR performance is directly proportional to angle of incident … …Journal of Computer Science, Vol. 8, Issue 1 · 2 Nov 2011 · 7,479 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReal-Time Volume Shadow using Visible-Non Visible AlgorithmHoshang Kolivand, Mohd Shahrizal Sunar, Azam Amirshakarami, Zhila RanjbariProblem statement: Shadows are most important effect to make realistic games and visually appealing images, but they are poor in frame per second. Silhouette detection is most important phases to create real-time shadow. Approach: Present study describes a real-time shadow generated with volume shadow algorithm using Visible-Non Visible algorithm (VNV) in virtual environment illuminated by a movable light source to … …Journal of Computer Science, Vol. 7, Issue 7 · 28 Jun 2011 · 6,988 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleABSENCE OF VISIBLE TOXIC EFFECTS ACCOMPANYING THE SHORT-TERM ADMINISTRATION OF AN AQUEOUS EXTRACT OF ALLIUM SATIVA LINN. IN MALE SPRAGUE-DAWLEY RATSJ. Asiedu-Gyekye Isaac, Awortwe Charles, A. Antwi DanielAllium sativum is cultivated in the northern part of Ghana and has gained widespread use as chemoprotective, in curing hypertension, impotence and erectile dysfunction. The multipurpose use together with its aphrodisiac activity has resulted in the widespread use of this plant medicine both in meals and as herbal medications. Safety assessment of this plant however is rare. The present study … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 1 · 30 Jan 2014 · 7,577 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAutomatic Target Recognition in Cluttered Visible ImageryM. Jasmine Pemeena Priyadarsini, K. Murugesan, Srinivasa Rao Inbathini et al.Detection of a target from among similar/dissimilar targets in a cluttered image is vital in automatic target recognition. A MACH filter is used for the target detection in cluttered imagery. The cluttered images are correlated using the filter formulated from training images. The target is expected to be detected in the first highest peak. MACH was assumed as an optimum … …Journal of Computer Science, Vol. 9, Issue 5 · 21 May 2013 · 6,925 accessesView PDFCite
Research ArticleOpen accessIn the keywordsObject Detection and Classification from Thermal Images Using Region based Convolutional Neural NetworkUsha Mittal, Sonal Srivastava, Priyanka ChawlaIn recent years, object detection and classification has gained so much popularity in different application areas like face detection, self- driving cars, pedestrian detection, security surveillance systems etc. The traditional detection methods like background subtraction, Gaussian Mixture Model (GMM), Support Vector Machine (SVM) have certain drawbacks like overlapping of objects, distortion due to smoke, fog, lightening conditions etc. In this … …Journal of Computer Science, Vol. 15, Issue 7 · 18 Jul 2019 · 9,448 accessesView PDFCite
Research ArticleOpen accessIn the keywordsConcealed Weapon Detection using Wavelet, Dual Tree Complex Wavelet Transform and Curvelet TransformAyush Dogra, Bhawna Goyal, Sunil Agrawal et al.In the field of military and law enforcement, detection and visualization of concealed weapons is a common practice. The infrared and visible cameras providing the information i.e., the characteristic visual features of the image and the thermal radiations are able to provide the complementary information like information about concealed objects or weapons. In this manuscript, we have proposed the integration … …Journal of Computer Science, Vol. 14, Issue 10 · 26 Oct 2018 · 7,252 accessesView PDFCite
