A Computational Intelligence Approach for Classifying Dental Caries in X-ray Images
Introduction Detecting dental caries in radiographs is a foundational task in preventive dentistry. The low contrast and overlapping structures in bite-wing and periapical X-ray images can obscure early lesions, making accurate classification a persistent challenge. A novel computational intelligence framework combines integrated fuzzy C-means clustering with feature reduction and a weighted matrix scheme to address…

A Computational Intelligence Approach for Classifying Dental Caries in X-ray Images Using Integrated Fuzzy C-means Clustering with Feature Reduction and a Weighted Matrix Scheme
Overview Dental caries detection in radiographs is a cornerstone of preventive dentistry. Traditional visual inspection can miss subtle demineralization, while raw image processing may struggle with low contrast and noise. This article outlines a computational intelligence framework that combines integrated fuzzy C-means clustering (FCM) with feature reduction and a weighted matrix scheme to classify dental…

Mathematicians Are Making Earth-Based Telescopes Rival Space Observatories
A Bold Leap for Ground-Based Astronomy For decades, astronomers have known that Earth’s atmosphere is both a blessing and a bane. It protects life, but its ever-changing temperature, pressure, and humidity distort light as it travels to ground-based telescopes. This turbulent blanket causes stars to twinkle and galaxies to smear into blur, especially for faint…
