This paper presents an approach based on Hidden Markov Chain (HMCs) to diagnose COVID-19, that we named HMC-COVID-19. To assess the performance of the proposed solution, we use a public dataset of chest X-RAY images. Our solution has been evaluated using the accuracy of prediction. The preliminary results are promising and can be further enhanced.Hidden Markov Chains (HMC)COVID-19 diagnosisHMC-COVID-19Image classificationConference paper10.1109/DASA59624.2023.10286601
