• Abstract summary: We propose a two-stage Convolutional Neural Network (CNN) based classification framework for detecting COVID-19 and CAP. The proposed framework achieved a slice-level classification accuracy of over 94% at identifying COVID-19 and CAP. The proposed framework has the potential to be an initial screening tool for differential diagnosis of COVID-19 and CAP.

• Abstract: We propose a two-stage Convolutional Neural Network (CNN) based classification framework for detecting COVID-19 and Community-Acquired Pneumonia (CAP) using the chest Computed Tomography (CT) scan images. In the first stage, an infection - COVID-19 or CAP, is detected using a pre-trained DenseNet architecture. Then, in the second stage, a fine-grained three-way classification is done using EfficientNet architecture. The proposed COVID+CAP-CNN framework achieved a slice-level classification accuracy of over 94% at identifying COVID-19 and CAP. Further, the proposed framework has the potential to be an initial screening tool for differential diagnosis of COVID-19 and CAP, achieving a validation accuracy of over 89.3% at the finer three-way COVID-19, CAP, and healthy classification. Within the IEEE ICASSP 2021 Signal Processing Grand Challenge (SPGC) on COVID-19 Diagnosis, our proposed two-stage classification framework achieved an overall accuracy of 90% and sensitivity of .857, .9, and .942 at distinguishing COVID-19, CAP, and normal individuals respectively, to rank first in the evaluation.

  An effective strategy to mitigate the COVID-19 pandemic involves integrating testing to identify infected individuals. While RT-PCR is considered the gold standard for diagnosing COVID-19, it has some limitations such as the risk of false negatives. This paper introduces a novel Deep Learning Diagnosis System that integrates pre-trained Deep Conal Neural Networks (DCNNs) within an ensemble learning framework.

  We seek to evaluate the detection performance of a rapid primary screening tool of Covid-19 based on the cough sound from 8,380 clinically validated samples. Our proposed generic method is an algorithm based on Empirical Mode Decomposition (EMD) with subsequent classification based on a tensor of audio features. Two different versions of DeepCough based on the number of tensor dimensions, i.e. DeepCough2D and DeepCough3D, have been investigated.

  A cascaded system is proposed to segment the lung, detect, localize, and quantify COVID-19 infections from CT images. The proposed system can reliably localize infection of various shapes and sizes, especially small infection regions. The system was able to discriminate between different severity levels of COVID-19 infection over a dataset of 1,110 subjects.
