The COVID-19 pandemic is a global, national, and local public health concern which has caused significant outbreak in all countries regions for both males females around the world. Automated detection of lung infections their boundaries from medical images offers great potential to augment patient treatment healthcare strategies tackling its impacts. Detecting this disease CT scan perhaps one fastest ways diagnose patients. However, finding presence infected tissues segment them slices faces numerous challenges, including similar adjacent tissues, vague boundary, erratic infections. To eliminate these obstacles, we propose two-route convolutional neural network (CNN) by extracting global features detecting classifying infection images. Each pixel image classified into normal tissues. For improving classification accuracy, used two different fuzzy c -means clustering directional pattern (LDN) encoding methods represent input differently. This allows us find more complex image. overcome overfitting problems due small samples, an augmentation approach utilized. results demonstrated that proposed framework achieved precision 96%, recall 97%, id="M2">F score, average surface distance (ASD) id="M3">2.8±0.3 mm, volume overlap error (VOE) id="M4">5.6±1.2% .

Over the past decade, convolutional neural networks (CNN) have shown very competitive performance in medical image analysis tasks, such as disease classification, tumor segmentation, and lesion detection. CNN has great advantages extracting local features of images. However, due to locality convolution operation, it cannot deal with long-range relationships well. Recently, transformers been applied computer vision achieved remarkable success large-scale datasets. Compared natural images, multi-modal images explicit important dependencies, effective fusion strategies can greatly improve deep models. This prompts us study transformer-based structures apply them Existing network architectures require datasets achieve better performance. imaging are relatively small, which makes difficult pure analysis. Therefore, we propose TransMed for classification. combines transformer efficiently extract low-level establish dependencies between modalities.

Diagnosis is a critical preventive step in Coronavirus research which has similar manifestations with other types of pneumonia. CT scans and X-rays play an important role that direction. However, processing chest images using them to accurately diagnose COVID-19 computationally expensive task. Machine Learning techniques have the potential overcome this challenge. This article proposes two optimization algorithms for feature selection classification COVID-19. The proposed framework three cascaded phases. Firstly, features are extracted from Convolutional Neural Network (CNN) named AlexNet. Secondly, algorithm, Guided Whale Optimization Algorithm (Guided WOA) based on Stochastic Fractal Search (SFS), then applied followed by balancing selected features. Finally, voting classifier, WOA Particle Swarm (PSO), aggregates different classifiers' predictions choose most voted class. increases chance individual classifiers, e.g. Support Vector (SVM), Networks (NN), k-Nearest Neighbor (KNN), Decision Trees (DT), show significant discrepancies. Two datasets used test model: containing clinical findings positive negative algorithm (SFS-Guided compared widely recent literature validate its efficiency. classifier (PSO-Guided-WOA) achieved AUC (area under curve) 0.995 superior classifiers terms performance metrics. Wilcoxon rank-sum, ANOVA, T-test statistical tests statistically assess quality as well.

Coronavirus disease 2019 (COVID-19) is an ongoing global pandemic that has spread rapidly since December 2019. Real-time reverse transcription polymerase chain reaction (rRT-PCR) and chest computed tomography (CT) imaging both play important role in COVID-19 diagnosis. Chest CT offers the benefits of quick reporting, a low cost, high sensitivity for detection pulmonary infection. Recently, deep-learning-based computer vision methods have demonstrated great promise use medical applications, including X-rays, magnetic resonance imaging, imaging. However, training deep-learning model requires large volumes data, staff faces risk when collecting data due to infectivity disease. Another issue lack experts available labeling. In order meet requirements we propose image synthesis approach based on conditional generative adversarial network can effectively generate high-quality realistic images tasks. Experimental results show proposed method outperforms other state-of-the-art with generated indicates promising various machine learning applications semantic segmentation classification.
