It is obvious that such a combination between deep features and a feature selection algorithm can be efficient in several image classification tasks. Syst. The main purpose of Conv. The largest features were selected by SMA and SGA, respectively. This dataset currently contains hundreds of frontal view X-rays and is the largest public resource for COVID-19 image and prognostic data, making it a necessary resource to develop and evaluate tools to aid in the treatment of CO VID-19. Decis. Moreover, a multi-objective genetic algorithm was applied to search for the optimal features subset. The evaluation showed that the RDFS improved SVM robustness against reconstruction kernel and slice thickness. Deep cnns for microscopic image classification by exploiting transfer learning and feature concatenation. \(Fit_i\) denotes a fitness function value.

The results showed that the proposed approach showed better performances in both classification accuracy and the number of extracted features that positively affect resource consumption and storage efficiency. Google Scholar. The proposed COVID-19 X-ray classification approach starts by applying a CNN (especially, a powerful architecture called Inception which pre-trained on Imagnet dataset) to extract the discriminant features from raw images (with no pre-processing or segmentation) from the dataset that contains positive and negative COVID-19 images. Comput. (2) To extract various textural features using the GLCM algorithm. J. Propose similarity regularization for improving C. 9, 674 (2020). The combination of SA and GA showed better performances than the original SA and GA. Narayanan et al.33 proposed a fuzzy particle swarm optimization (PSO) as an FS method to enhance the classification of CT images of emphysema. It also contributes to minimizing resource consumption which consequently, reduces the processing time. Classification Covid-19 X-Ray Images | by Falah Gatea | Medium 500 Apologies, but something went wrong on our end. Also, they require a lot of computational resources (memory & storage) for building & training. Furthermore, the proposed GRAY+GRAY_HE+GRAY_CLAHE image representation was evaluated on two different datasets, SARS-CoV-2 CT-Scan and New_Data_CoV2, where it was found to be superior to RGB . Average of the consuming time and the number of selected features in both datasets. Purpose The study aimed at developing an AI . In general, MPA is a meta-heuristic technique that simulates the behavior of the prey and predator in nature37. Covid-19 dataset.

A deep feature learning model for pneumonia detection applying a combination of mRMR feature selection and machine learning models. 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 focus of this study is to evaluate and examine a set of deep learning transfer learning techniques applied to chest radiograph images for the classification of COVID-19, normal (healthy), and pneumonia. In this paper, Inception is applied as a feature extractor, where the input image shape is (229, 229, 3). The proposed cascaded system is proposed to segment the lung, detect, localize, and quantify COVID-19 infections from computed tomography images, which can reliably localize infections of various shapes and sizes, especially small infection regions, which are rarely considered in recent studies. Table4 show classification accuracy of FO-MPA compared to other feature selection algorithms, where the best, mean, and STD for classification accuracy were calculated for each one, besides time consumption and the number of selected features (SF). As Inception examines all X-ray images over and over again in each epoch during the training, these rapid ups and downs are slowly minimized in the later part of the training. The authors declare no competing interests. Very deep convolutional networks for large-scale image recognition. You are using a browser version with limited support for CSS. A.A.E. Methods: We employed a public dataset acquired from 20 COVID-19 patients, which . To evaluate the performance of the proposed model, we computed the average of both best values and the worst values (Max) as well as STD and computational time for selecting features.

Accordingly, the FC is an efficient tool for enhancing the performance of the meta-heuristic algorithms by considering the memory perspective during updating the solutions. Although convolutional neural networks (CNNs) is considered the current state-of-the-art image classification technique, it needs massive computational cost for deployment and training. PubMed The 30-volume set, comprising the LNCS books 12346 until 12375, constitutes the refereed proceedings of the 16th European Conference on Computer Vision, ECCV 2020, which was planned to be held in Glasgow, UK, during August 23-28, 2020. All classication models ever, the virus mutates, and new variants emerge and dis- performed better in classifying the Non-COVID-19 images appear. In the current work, the values of k, and \(\zeta\) are set to 2, and 2, respectively. For the exploration stage, the weibull distribution has been applied rather than Brownian to bost the performance of the predator in stage 2 and the prey velocity in stage 1 based on the following formula: Where k, and \(\zeta\) are the scale and shape parameters. Also, some image transformations were applied, such as rotation, horizontal flip, and scaling. Knowl.

In Medical Imaging 2020: Computer-Aided Diagnosis, vol. Automatic CNN-based Chest X-Ray (CXR) image classification for detecting Covid-19 attracted so much attention. Deep learning plays an important role in COVID-19 images diagnosis. Lett. The Softmax activation function is used for this purpose because the output should be binary (positive COVID-19 negative COVID-19). However, some of the extracted features by CNN might not be sufficient, which may affect negatively the quality of the classification images. In this paper, after applying Chi-square, the feature vector is minimized for both datasets from 51200 to 2000. The whole dataset contains around 200 COVID-19 positive images and 1675 negative COVID19 images. The combination of Conv. The results indicate that all CNN-based architectures outperform the ViT-based architecture in the binary classification of COVID-19 using CT images. Two real datasets about COVID-19 patients are studied in this paper. (22) can be written as follows: By taking into account the early mentioned relation in Eq. The updating operation repeated until reaching the stop condition. Also, other recent published works39, who combined a CNN architecture with Weighted Symmetric Uncertainty (WSU) to select optimal features for traffic classification. Stage 2: The prey/predator in this stage begin exploiting the best location that detects for their foods. . Four measures for the proposed method and the compared algorithms are listed.

The MCA-based model is used to process decomposed images for further classification with efficient storage. For example, Lambin et al.7 proposed an efficient approach called Radiomics to extract medical image features. (23), the general formulation for the solutions of FO-MPA based on FC memory perspective can be written as follows: After checking the previous formula, it can be detected that the motion of the prey becomes based on some terms from the previous solutions with a length of (m), as depicted in Fig. Hence, the FC memory is applied during updating the prey locating in the second step of the algorithm to enhance the exploitation stage. So, transfer learning is applied by transferring weights that were already learned and reserved into the structure of the pre-trained model, such as Inception, in this paper. (5). According to the formula10, the initial locations of the prey and predator can be defined as below: where the Elite matrix refers to the fittest predators. 6 (left), for dataset 1, it can be seen that our proposed FO-MPA approach outperforms other CNN models like VGGNet, Xception, Inception, Mobilenet, Nasnet, and Resnet. In addition, the good results achieved by the FO-MPA against other algorithms can be seen as an advantage of FO-MPA, where a balancing between exploration and exploitation stages and escaping from local optima were achieved.
