The corona virus is already spread around the world in many countries, and it has taken many lives. Furthermore, the world health organization (WHO) has announced that COVID-19 has reached the global epidemic stage. Early and reliable diagnosis using chest CT-scan can assist medical specialists in vital circumstances. In this study, we introduce a computer aided diagnosis (CAD) web service to detect COVID-19 based on chest CT- scan images and deep learning approach. A public database containing 746 participants were used in this experiment. A novel combination of the Densely connected convolutional network (DenseNet) in order to extract spatial features and a Nu-SVM was applied on the feature maps were implemented to distinguish between COVID-19 and healthy controls. A number of well-known deep neural network architectures consisting of ResNet, Inception and MobileNet were also applied and compared to main model in order to prove efficiency of the hybrid system. The developed flask web service in this research uses the trained model to provide a RESTful COVID-19 detector, which takes only 39 milliseconds to process one image. The source code is also available 2. The proposed methodology achieved 90.80 89.76 Based on the findings, it can be inferred that it is feasible to use the proposed technique as an automated tool for diagnosis of COVID-19.
