Recently, many diseases have negatively impacted people's lifestyles. Among these, knee osteoarthritis (OA) has been regarded as the primary cause of activity restriction and impairment, particularly in older people. Therefore, quick, accurate, low-cost computer-based tools for early prediction OA patients are urgently needed. In this paper, part addressing issue, we developed a new method to efficiently diagnose classify severity based on X-ray images (i.e., binary multiclass) order study impact different class-based, which not yet addressed previous studies. This will provide physicians with variety deployment options future. Our proposed models basically divided into two frameworks applying pre-trained convolutional neural networks (CNN) feature extraction well fine-tuning CNN using transfer learning (TL) method. addition, traditional machine (ML) classifier is used exploit enriched space achieve better classification performance. first one, five classes-based extraction, principal component analysis (PCA) dimensionality reduction, support vector (SVM) classification.

Published: March 1, 2024

Abstract The global spread of epidemic lung diseases, including COVID-19, underscores the need for efficient diagnostic methods. Addressing this, we developed and tested a computer-aided, lightweight Convolutional Neural Network (CNN) rapid accurate identification diseases from 29,131 aggregated Chest X-ray (CXR) images representing seven disease categories. Employing five-fold cross-validation method to ensure robustness our results, CNN model, optimized heterogeneous embedded devices, demonstrated superior performance. It achieved 98.56% accuracy, outperforming established networks like ResNet50, NASNetMobile, Xception, MobileNetV2, DenseNet121, ViT-B/16 across precision, recall, F1-score, AUC metrics. Notably, model requires significantly less computational power only 55 minutes average training time per fold, making it highly suitable resource-constrained environments. This study contributes developing efficient, in medical image analysis, underscoring their potential enhance point-of-care processes.
