The rapid and accurate detection of COVID-19 (coronavirus disease 2019) from normal and pneumonia chest x-ray images is essential for timely diagnosis and treatment. The overlapping features in radiology images make it challenging for radiologists to distinguish COVID-19 cases. This research study investigates the effectiveness of combining local binary pattern (LBP) and histogram of oriented gradients (HOG) features with machine learning algorithms to differentiate COVID-19 from normal and pneumonia cases using chest x-rays. The proposed hybrid fusion model "RadientFusion-XR" utilizes LBP and HOG features with shallow learning algorithms. The proposed hybrid HOG-LBP fusion model, RadientFusion-XR, detects COVID-19 cases from normal and pneumonia classes. This fusion model provides a comprehensive representation, enabling more precise differentiation among the three classes. This methodology presents a promising and efficient tool for early COVID-19 and pneumonia diagnosis in clinical settings, with potential integration into automated diagnostic systems. The findings highlight the potential of this hybrid feature extraction and a shallow learning approach to improve diagnostic accuracy in chest x-ray analysis significantly. The hybrid model using LBP and HOG features with an ensemble model achieved an exceptional accuracy of 99% for binary class (COVID-19, normal) and 97% for multi-class (COVID-19, normal, pneumonia), respectively. These results demonstrate the efficacy of our hybrid approach in enhancing feature representation and achieving superior classification accuracy. The proposed RadientFusion-XR model with hybrid feature extraction and shallow learning approach significantly increases the accuracy of COVID-19 and pneumonia diagnoses from chest x-rays. The interpretable nature of RadientFusion-XR, alongside its effectiveness and explainability, makes it a valuable tool for clinical applications, fostering trust and enabling informed decision-making by healthcare professionals.
从正常胸部X光图像和肺炎胸部X光图像中快速准确地检测出2019冠状病毒病(COVID-19)对于及时诊断和治疗至关重要。放射图像中的重叠特征使得放射科医生难以区分COVID-19病例。本研究调查了将局部二值模式(LBP)和方向梯度直方图(HOG)特征与机器学习算法相结合,以利用胸部X光区分COVID-19与正常和肺炎病例的有效性。所提出的混合融合模型“RadientFusion-XR”利用LBP和HOG特征以及浅层学习算法。所提出的混合HOG-LBP融合模型RadientFusion-XR可从正常和肺炎类别中检测出COVID-19病例。这种融合模型提供了全面的表征,能够在这三类之间进行更精确的区分。该方法为临床环境中早期COVID-19和肺炎的诊断提供了一种有前景且高效的工具,具有集成到自动诊断系统中的潜力。研究结果突出了这种混合特征提取和浅层学习方法在显著提高胸部X光分析诊断准确性方面的潜力。使用LBP和HOG特征与集成模型的混合模型在二分类(COVID-19、正常)中分别达到了99%的卓越准确率,在多分类(COVID-19、正常、肺炎)中达到了97%的准确率。这些结果证明了我们的混合方法在增强特征表征和实现卓越分类准确率方面的有效性。所提出的具有混合特征提取和浅层学习方法的RadientFusion-XR模型显著提高了从胸部X光诊断COVID-19和肺炎的准确率。RadientFusion-XR的可解释性,连同其有效性和可解释性,使其成为临床应用的宝贵工具,增强了信任并使医疗专业人员能够做出明智的决策。
