Research ArticleOpen accessEvery word in the titleCombining SURF and MSER along with Color Features for Image Retrieval System Based on Bag of Visual WordsHeba A. ElnemrContent-Based Image Retrieval (CBIR) has received an extensive attention from researchers due to the rapid growing and widespread of image databases. Despite the massive research efforts consumed for CBIR, the completely satisfactory results have not yet been attained. In this article, we offer a new CBIR technique that relies on extracting Speeded Up Robust Features (SURF) and Maximally Stable Extremal … …Journal of Computer Science, Vol. 12, Issue 4 · 9 May 2016 · 7,709 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFeature Extraction Method for Improving Speech Recognition in Noisy EnvironmentsYoussef Zouhir, Kaïs OuniThe paper presents a feature extraction method, named as Normalized Gammachirp Cepstral Coefficients (NGCC) that incorporates the properties of the peripheral auditory system to improve robustness in noisy speech recognition. The proposed method is based on a second order low-pass filter and normalized gammachirp filterbank to emulate the mechanisms performed in the outer/middle ear and cochlea. The speech recognition performance … …Journal of Computer Science, Vol. 12, Issue 2 · 25 Mar 2016 · 7,873 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComponents Affecting Dental Fear in Adults: A Cross Sectional StudyEugenia M. Diaz Almenara, Antonio Castaño Seiquer, Laura Sanmartin Galindo et al.The estimated prevalence of extreme dental fear and anxiety is 40% among the adult population. Patient expressed fear of the dentist is rarely used in clinical practice to assess patient concerns. The present study was carried out to identify the risk factors associated to fear of the dentist and the frequency of visits to the dental clinic. The study comprised … …Current Research in Dentistry, Vol. 8, Issue 1 · 25 Feb 2016 · 13,816 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Role of Perspective-Taking on Ability to Recognize FearAndrea Trubanova, Inyoung Kim, Marika C. Coffman et al.Impairment in the ability to detect certain emotions, such as fear, is linked to multiple disorders and follows a pattern of inter-individual variability and intra-individual stability over time. Deficits in fear recognition are often related to social and interpersonal difficulties but the mechanisms by which this processing deficit might occur are not well understood. One potential mechanism through which impaired … …Current Research in Psychology, Vol. 6, Issue 2 · 12 Jan 2016 · 8,679 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Novel Distinguishability Based Weighted Feature Selection Algorithms for Improved Classification of Gene Microarray DatasetJ. Jeyachidra, M. PunithavalliData mining played vital role in comprehending, analyzing, understanding and interpreting microarray technology expression data. That includes search for genes that had similar or correlated patterns of expression. For that, the feature selection was one of the frequently used important techniques for data preprocessing. Many feature selection algorithms had been developed. Yet the persisting problem was in selecting optimal subset … …Journal of Computer Science, Vol. 11, Issue 2 · 2 Feb 2015 · 6,380 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA NEW APPROACH OF LOCAL FEATURE DESCRIPTORS USING MOMENT INVARIANTSLee-Yeng Ong, Siong-Hoe Lau, Voon-Chet KooMoment invariants have been widely introduced in recognizing planar objects for a few decades. This is due the robustness of moment function in distinguishing the original identity of object under various two Dimensional (2D) transformations. A set of moments computed from a planar images, represents the global description of an object's shape and geometrical features of an image. Since global … …Journal of Computer Science, Vol. 10, Issue 12 · 29 Dec 2014 · 7,957 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA COMPARATIVE STUDY OF COMBINED FEATURE SELECTION METHODS FOR ARABIC TEXT CLASSIFICATIONAisha Adel, Nazlia Omar, Adel Al-ShabiText classification is a very important task due to the huge amount of electronic documents. One of the problems of text classification is the high dimensionality of feature space. Researchers proposed many algorithms to select related features from text. These algorithms have been studied extensively for English text, while studies for Arabic are still limited. This study introduces an investigation … …Journal of Computer Science, Vol. 10, Issue 11 · 20 Dec 2014 · 8,439 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Impact of Oath Writing Style on Stylometric Features and Machine Learning ClassifiersAhmad Alqurneh, Aida MustaphaComputational stylometry is the field that studies the distinctive style of a written text using computational tasks. The first task is how to define quantifiable measures in a text and the second is to classify the text into a predefined category. This study propose a stylometric features selection approach evaluated by machine learning algorithms to find the finest of the … …Journal of Computer Science, Vol. 11, Issue 2 · 9 Sep 2014 · 7,148 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFINGER KNUCKLE-PRINT IDENTIFICATION BASED ON LOCAL AND GLOBAL FEATURE EXTRACTION USING SDOSTN. B. Mahesh Kumar, K. PremalathaFinger knuckle-print biometric system has widely used in modern e-world. The region of interest is needed as the key for the feature extraction in a good biometric system. The symmetric discrete orthonormal stockwell transform provides the computational efficiency and multi-scale information of wavelet transforms, while providing texture features in terms of Fourier frequencies. It outperforms leading wavelet-based texture analysis methods. … …American Journal of Applied Sciences, Vol. 11, Issue 6 · 3 Apr 2014 · 6,931 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInteraction of γ Aminobutyric Acid B Receptors and Electromagnetic Field in the Fear ResponseM. Taherianfard, A. Bahaodini, M. Fazeli, S. Karimi HaghighiOne of the most neurotransmission system consistently linked with fear response is GABAergic system. GABA through GABAB receptor can influence fear response. The aim of the present investigation was to examine the effect of IP injection of baclofen (GABAB agonist) and CGP35348 (GABAB antagonist) along with EMF exposure on frequency of fear response. Fifty adult male rats weighing 180-200 g … …Neuroscience International, Vol. 4, Issue 2 · 1 Apr 2014 · 6,696 accessesView PDFCite
