@article { , title = {Accelerated Diagnosis of Novel Coronavirus (COVID-19)—Computer Vision with Convolutional Neural Networks (CNNs)}, abstract = {Early detection and diagnosis of COVID-19, as well as exact separation of non-COVID-19 cases in a non-invasive manner in the earliest stages of the disease, are critical concerns in the current COVID-19 pandemic. Convolutional Neural Network (CNN) based models offer a remarkable capacity for providing an accurate and efficient system for detection and diagnosis of COVID-19. Due to the limited availability of RT-PCR (Reverse transcription-polymerase Chain Reaction) test in developing countries, imaging-based techniques could offer an alternative and affordable solution to detect COVID-19 symptoms. This case study reviewed the current CNN based approaches and investigated a custom-designed CNN method to detect COVID-19 symptoms from CT (Computed Tomography) chest scan images. This study demonstrated an integrated method to accelerate the process of classifying CT scan images. In order to improve the computational time, a hardware-based acceleration method was investigated and implemented on a reconfigurable platform (FPGA). Experimental results highlight the difference between various approximations of the design, providing a range of design options corresponding to both software and hardware. The FPGA based implementation involved a reduced pre-processed feature vector for the classification task which is a unique advantage for this particular application. To demonstrate the applicability of the proposed method, results from the CPU based classification and the FPGA were measured separately and compared retrospectively.}, doi = {10.3390/electronics11071148}, issue = {7}, journal = {Electronics}, publicationstatus = {Published}, publisher = {MDPI}, url = {http://researchrepository.napier.ac.uk/Output/2861022}, volume = {11}, keyword = {Convolutional Neural Networks (CNN), computer vision, reconfigurable architectures, intelligent system design, COVID-19, embedded devices}, year = {2022}, author = {Ghani, Arfan and Aina, Akinyemi and See, Chan Hwang and Yu, Hongnian and Keates, Simeon} }
