Vision Transformer-based Model for Severity Quantification of Lung Pneumonia Using Chest X-ray Images
This work addresses the need for automated, efficient severity assessment of lung pneumonia for healthcare professionals, though it appears incremental as it builds on existing Vision Transformer methods.
The authors tackled the problem of quantifying the severity of COVID-19 and other lung diseases from chest X-ray images by proposing a Vision Transformer-based model called ViTReg-IP, which achieved peak performance with high generalizability at relatively low computational cost.
To develop generic and reliable approaches for diagnosing and assessing the severity of COVID-19 from chest X-rays (CXR), a large number of well-maintained COVID-19 datasets are needed. Existing severity quantification architectures require expensive training calculations to achieve the best results. For healthcare professionals to quickly and automatically identify COVID-19 patients and predict associated severity indicators, computer utilities are needed. In this work, we propose a Vision Transformer (ViT)-based neural network model that relies on a small number of trainable parameters to quantify the severity of COVID-19 and other lung diseases. We present a feasible approach to quantify the severity of CXR, called Vision Transformer Regressor Infection Prediction (ViTReg-IP), derived from a ViT and a regression head. We investigate the generalization potential of our model using a variety of additional test chest radiograph datasets from different open sources. In this context, we performed a comparative study with several competing deep learning analysis methods. The experimental results show that our model can provide peak performance in quantifying severity with high generalizability at a relatively low computational cost.
