Research ArticleOpen accessEvery word in the titleRadial Basis Function Networks and Contrast-Limited Adaptive Histogram Equalization Filter Based Early-Stage Breast Cancer Detection TechniquesAnitha Ponraj, Aroul CanessaneBreast cancer is one of the most common types of cancer that kills women. When cells become uncontrollably large, cancer develops. As a result, detecting and classifying breast cancer in its early stages is essential so that patients can take the appropriate precautions. On the other hand, mammography images have relatively low sensitivity and effectiveness in detecting breast cancer. Furthermore, … …Journal of Computer Science, Vol. 19, Issue 6 · 25 May 2023 · 5,613 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSelf-Supervised Contrastive Learning for Steering Angle Prediction in Autonomous Driving SimulationsMaxson Phang, Suryadiputra LiawatimenaPredicting steering angles is a crucial task in autonomous driving, with end-to-end deep learning being a widely used approach. However, such models often suffer from overfitting to learned trajectories, limiting their generalization to new data. To address this, self-supervised contrastive learning is explored as an alternative, allowing models to learn meaningful representations without labeled data. The primary objective is to … …Journal of Computer Science, Vol. 21, Issue 9 · 20 Oct 2025 · 2,581 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Efficient Method for Contrast Enhancement in Still Images using Histogram Modification FrameworkC. G. Ravichandran, V. MagudeeswaranProblem statement: Image enhancement improves an image appearance by increasing dominance of some features or by decreasing ambiguity between different regions of the image. Histogram based image enhancement technique is mainly based on equalizing the histogram of the image and increasing the dynamic range corresponding to the image. Approach: Histogram Equalization is widely used in different ways to perform contrast … …Journal of Computer Science, Vol. 8, Issue 5 · 2 Mar 2012 · 8,007 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRobust Adversarial Attack Detection via Generative Adversarial Network With Residual Multi-Layer Aggregation Based Contrastive Loss FunctionAmudha Gopalakrishnan, Nalini JosephAdversarial attacks in medical imaging refer to subtle modifications to images that mislead diagnostic systems, resulting in inaccurate diagnoses and assessments. These attacks exploit vulnerabilities in image processing, leading to misclassification or altered visual features that often go unnoticed. This raises serious concerns about the security and reliability of medical diagnosis, directly impacting clinical decision-making and patient safety. This research … …Journal of Computer Science, Vol. 22, Issue 1 · 10 Feb 2026 · 1,742 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleACCURATE AND FAST PUPIL LOCALIZATION USING CONTRAST STRETCHING, SEED FILLING AND CIRCULAR GEOMETRICAL CONSTRAINTSIman A. Saad, Loay E. George, Ahmad A. TayyarIris segmentation is the most contested issue in the iris recognition system, since noise and poor image quality can significantly affect accuracy of iris localization stage. Therefore, very careful attention has to be paid for the segmentation process if only an accurate result is expected. This study presents a new method for precise pupil detection capable of handling the unconstrained … …Journal of Computer Science, Vol. 10, Issue 2 · 16 Nov 2013 · 7,240 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePHASEY: A Contrastive Learning Approach for Enhanced Human Gait Phases RecognitionUrvashi, Deepak Kumar, Vinay Kukreja, Ayush DograHuman gait has gained much attention in behavioral biometrics as it possesses unique and distinctive characteristics. Gait phases, which describe the different patterns of human walking, are significant for the analysis and understanding of movement in an individual. Hence, the identification of gait phases is important for the accurate determination and interpretation of walking patterns, ranging from healthcare and security … …Journal of Computer Science, Vol. 21, Issue 8 · 16 Sep 2025 · 4,638 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleContrastive Analysis of Stretched Collocations with Get and Take: Their use and Pedagogical ImplicationsSilvia Molina PlazaThis paper explores the pedagogical implications of contrastive analyses of light verb constructions containing get and take in English and Spanish based on electronic corpora, the British National Corpus (BNC) and the Corpus de Referencia del Español Actual (CREA). The main tenets of collocations from a contrastive perspective-and the points of contact and departure between both languages-are discussed prior to … …Journal of Social Sciences, Vol. 11, Issue 3 · 23 Jul 2015 · 8,092 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMolecular Characterization of Banana (AA) Diploids with Contrasting Levels of Black and Yellow Sigatoka ResistanceClaudia Fortes Ferreira, Sebastiao Oliveira Silva, Nivia Paula Damasceno Sobrinho et al.Most banana cultivars are susceptible to many diseases, whereas Sigatoka leads to greatest yield losses. One of the strategies to overcome this disease is thorough banana genetic breeding which consists in the obtainment of improved (AA) diploids which are then crossed with triploids obtaining (AAAB) tetraploid disease resistant bananas also presenting other important agronomic characteristics. The prior knowledge of the … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,652 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMultidimensional Sustainability Assessment of Marica Goat Farming in Contrasting Agroecological Zones of South Sulawesi, IndonesiaA. Amidah Amrawaty, Indrawirawan, Agustina Abdullah, Muhammad Ihsan Andi DagongThe Marica goat, a local breed in South Sulawesi, Indonesia, is highly adaptable to arid environments but faces a continuous population decline. This study assessed the sustainability of Marica goat farming in Jeneponto Regency, South Sulawesi, Indonesia. The research focusing on two agroecological zones: the mountainous Kelara District and the coastal Tamalatea District. A rapid appraisal approach was employed, integrating … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 3 · 7 Nov 2025 · 2,308 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleContrasting Effects of Metal Contaminations and Soil Liming on Cations Exchange Capacity and Global DNA Methylation in Betula papyrifera Populations from a Mining RegionGabriel Theriault, Kabwe NkongoloThe Greater Sudbury Region in Northern Ontario (Canada) has been one of the most contaminated regions in the world. Soil liming with dolomitic limestone applications has decreased significantly the level of soil acidity resulting in forest regeneration. This reclamation process does not affect the level of soil metal contamination but results in metals availability decrement. The coping mechanisms of birch … …American Journal of Environmental Sciences, Vol. 12, Issue 2 · 11 Apr 2016 · 7,535 accessesView PDFCite
