Early accurate diagnosis of disease, known as most "insidious" among eye diseases, important. In this study, glaucoma prediction application was performed from high-resolution fundus photographs taken open-source database. Correlation, energy, homogeneity, contrast ...
Currently, improving the identification of COVID-19 with help computer vision and artificial intelligence has received great attention from researchers. This paper proposes a novel method for automatic detection based on chest CT to radiologists improve speed reliability tests diagnosing COVID-19. Our algorithm is hybrid approach Gray-level Cooccurrence Matrix Genetic Algorithm. The (GLCM) was ...
Site-specific investigations of the role of radiomics in cancer diagnosis and therapy are emerging. We evaluated the reproducibility of radiomic features extracted from 18 Flourine-fluorodeoxyglucose (18 F-FDG) PET images for three parameters: manual versus computer-aided segmentation methods, gray-level discretization, and PET image reconstruction algorithms. Our cohort consisted of pretreatme...
