NextFin news, Pulmonary diseases such as pneumonia, tuberculosis, and COVID-19 continue to pose health challenges worldwide. In response, a research team has introduced a new deep learning model called Adaptive Multiscale Fusion Net (AMFNet) designed to accurately identify pulmonary diseases from chest X-ray images.
The AMFNet model incorporates a lightweight multiscale feature extraction network named MFNet, which captures fine-grained image details efficiently with low computational cost. It combines features from MFNet and ResNet50 through an adaptive fusion mechanism to enhance feature diversity and robustness. The model also integrates specialized modules—SCConv, AFF, and MFReLU—to improve feature discrimination while maintaining computational efficiency.
Chest X-ray imaging is a rapid, non-invasive, and relatively inexpensive method for screening pulmonary diseases. However, manual diagnosis by imaging physicians can be time-consuming and prone to errors, especially when symptoms are subtle in early disease stages. The AMFNet aims to reduce the diagnostic burden by providing precise recognition of pulmonary medical images.
The model's design includes a Fusion Basic Block for wide-area coding and a Multiscale Layer that processes different semantic information levels, enabling the network to focus effectively on relevant features. Additionally, AMFNet employs a model fusion strategy to avoid local optima during training, reducing errors and uncertainties associated with individual models.
Experimental results on publicly available chest radiography datasets demonstrate that AMFNet balances accuracy and parameter efficiency when compared with popular convolutional neural network (CNN) and Transformer-based models. The research outlines the model's architecture, training methods, and evaluation, providing a comprehensive approach to pulmonary disease recognition using deep learning.
This development follows extensive research efforts in applying machine learning and deep learning techniques to medical image analysis, particularly for pulmonary disease classification. The AMFNet contributes to this field by addressing limitations of single-model approaches and enhancing diagnostic reliability through adaptive multiscale feature fusion.
