The coronavirus spread rapidly in the world and caused the disease of Covid-19. The proposed research was conducted with the aim of classifying people with Covid-19 from other people. Among all the imaging modalities, lung ultrasound images were used to diagnose covid-19. The open source Point-Care-of-Ultrasound (POCUS) database was collected, which contained 59 Lung Ultrasound (LUS) images. In this research, KNN classifier with K-fold cross validation was used to classify the feature matrix obtained from Fractional B-spline Wavelet Transform (FBSWT). In the proposed method, Block-Matching and 3D filtering (BM3D) filter was used in some methods, which had acceptable results. The proposed method was used to classify healthy people from patients with Covid-19. The results show that when the features based on the wavelet transform (WT) are used, the proposed method can be achieved 90.90% sensitivity, 92.30% specificity, and 91.42% accuracy. While the features extracted from FBSWT show that the proposed method can be achieved 95.45% sensitivity, 93.30% specificity, and 94.28% accuracy. Fractional transforms, especially the FBSWT, can be a useful tool for image processing. They can be used for various purposes such as detection and classification. By using FBSWT, it is possible to accurately diagnose the disease of covid-19.
