Research ArticleOpen accessIn the abstractSpeech Enhancement Algorithm Using Sub band Two Step Decision Directed Approach with Adaptive Weighting factor and Noise Masking ThresholdDeepa Dhanaskodi, Shanmugam ArumugamProblem statement: Speech Enhancement plays an important role in any of the speech processing systems like speech recognition, mobile communication, hearing aid. Approach: In this work, human perceptual auditory masking effect is incorporated into the single channel speech enhancement algorithm. The algorithm is based on a criterion by which the audible noise may be masked rather than being attenuated and … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 7,126 accessesView PDFCite
Research ArticleOpen accessIn the abstractBlack White Color and Gray Pixel Extraction ModelK. Selvam, B. PoornaThis is a design approach of software on image and pattern recognition, while eliminating the color and gray code of an image for comparison. This approach is quite effective for black and white and color images or scenes. Here we select particular part or parts of a given image and we compare with the contents of template-image (biometric) database. This … …Journal of Computer Science, Vol. 3, Issue 12 · 31 Dec 2007 · 6,862 accessesView PDFCite
Research ArticleOpen accessIn the abstractHumoral Immune Response in Tuberculous PleuritisPrabha C., Kripa V. Jalapathy, Sulochana D. DasTuberculous pleuritis is a good human model to understand the local and protective immune response against tuberculosis, due to the self-limitedness of the disease. Although the cellular immune response has been well characterised in tuberculous pleurisy, much less is known about the humoral immune response operating at the site of infection. To understand the humoral immune response, B cells were … …American Journal of Immunology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,518 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Challenge of the Hospitals and Health Care Systems in Preparation for Biological and Chemical Terrorism AttackEldo Ermenegildo Frezza MDIn the present study a few aspects of planning for terrorism events that expose large numbers of people to contamination are discussed. Many issues were considered as an absolute requirement for implementation of NBC response: 1) policy, 2) plan and 3) emergency department response to surge capacity. Key elements of the healthcare facility response plan include prompt recognition of the … …Journal of Social Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,390 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordTextual Figure Processing Method: A Systematic Literature ReviewWydyanto Yanto, Norshita Mat Nayan, Riza SulaimanA human transaction always involves figured documents that have high practical value and could be screened using Optical Character Recognition (OCR). Optical character recognition is a knowledge to process different types of documents and figures to become data that could be analyzed, stored in files, edited and written for different uses. Lately, researchers used a lot of methods to analyze … …American Journal of Applied Sciences, Vol. 21, Issue 1 · 26 Oct 2024 · 8,176 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHybrid SIFT-DCT Approach for Face Matching of BuddhaStatues: Addressing Negative Similarity Metrics with SHashingLinda Marlinda, Fikri Budiman et al.Art and cultural heritage rely on image processing techniques forpreservation and analysis. A key challenge in this study is accuratelydetecting highly similar Buddha faces despite variations in lighting, rotation,and minor facial differences. This paper proposes a Content-Based ImageRetrieval (CBIR) framework that integrates Discrete Cosine Transform(DCT) and Scale-Invariant Feature Transform (SIFT) to enhance face-matching accuracy. The system is tested on a … …Journal of Computer Science, Vol. 21, Issue 7 · 29 Jul 2025 · 3,483 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFall Detection Using the Histogram of Oriented Gradients and Decision-Based FusionMohamed Maher Ben Ismail, Arwa AlGabas, Ouiem BchirAs the number of fall incidents among elderly people and patients are continuously growing, researches boosted their researches to propose efficient automatic fall detection systems. In particular, they formulated the fall detection problem as a supervised learning task where some visual features are extracted from the video frames and used to automatically identify the position of a human as “Fall” … …Journal of Computer Science, Vol. 16, Issue 2 · 26 Feb 2020 · 7,500 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordSpeech Corpora for Different Languages: A Systematic ReviewVladimir Igorevich Fedoseev, Anton Aleksandrovich Konev, Natalia Sergeevna RepyukThe study of speech signals relies on carefully curated audio recordings, which are compiled and stored within specialized speech corpora. This article provides a comprehensive overview of such corpora across multiple languages, with particular focus on Russian, English, and Arabic. It notes that Russian and Arabic are represented by fewer corpora compared to the more extensive resources available for English. … …Journal of Computer Science, Vol. 22, Issue 1 · 2 Feb 2026 · 1,781 accessesView PDFCite
