Lilang Zheng, Jiaxuan Fang, Xiaorun Tang, Hanzhang Li, Jiaxin Fan, Tianyi Wang, Rui Zhou, Zhaoyan Yan: PVT-COV19D: COVID-19 Detection Through Medical Image Classification Based on Pyramid Vision Transformer. Computer Vision - ECCV 2020 16th European Conference, Glasgow, UK For example, Lambin et al.7 proposed an efficient approach called Radiomics to extract medical image features. The Softmax activation function is used for this purpose because the output should be binary (positive COVID-19 negative COVID-19). Pool layers are used mainly to reduce the inputs size, which accelerates the computation as well. Cohen, J.P., Morrison, P. & Dao, L. Covid-19 image data collection. In54, AlexNet pre-trained network was used to extract deep features then applied PCA to select the best features by eliminating highly correlated features. The main purpose of Conv. For instance,\(1\times 1\) conv. Also, image segmentation can extract critical features, including the shape of tissues, and texture5,6. 1. 11, 243258 (2007). & Cao, J.

Deep learning plays an important role in COVID-19 images diagnosis. As seen in Table1, we keep the last concatenation layer which contains the extracted features, so we removed the top layers such as the Flatten, Drop out and the Dense layers which the later performs classification (named as FC layer). Table2 shows some samples from two datasets. In Future of Information and Communication Conference, 604620 (Springer, 2020). Imaging Syst. Computational image analysis techniques play a vital role in disease treatment and diagnosis.
