Abstract
Accurate classification of bone fractures from medical images plays a crucial role in effective treatment and patient care, particularly in the case of wrist X-rays. However, the limited availability of labeled medical images poses a significant challenge in training deep learning models for fracture classification. In this paper, we proposed a novel lightweight convolutional neural network (CNN) architecture, LSNet, designed specifically for Siamese networks to classify bone fractures from a limited dataset of 193 wrist X-ray images. The Siamese network extracted features from the input images, which are then fed to machine learning classifiers such as Support Vector Machine, Logistic Regression, K-Nearest Neighbor, and Decision Tree for classification. We compared the performance of our proposed LSNet against existing lightweight CNN architectures, namely SqueezeNet, ShuffleNet, MnasNet, MobileNet, and DenseNet, all implemented in PyTorch. Our results demonstrated that LSNet is not only lighter than these existing models but also achieved superior performance, with the highest accuracy and F1 score of 85.6% and 85%, respectively. This study highlights the potential of LSNet as an efficient and accurate solution for bone fracture classification in clinical settings, particularly when dealing with limited medical image datasets.
