COVID-19 图像从多个公开资源如 Github、德国医学院和SIRM 收集而来,而正常及病毒性肺炎图像则来源于 Kaggle 的“Chest X-Ray Images (pneumonia)”数据库。所有图像均以 PNG 格式提供,其分辨率为1024×1024 像素或 256×256 像素。此数据集为从事 COVID-19 分类研究的学者提供了宝贵的参考资源。 数据集元信息...
In this paper, we propose a machine learning algorithm to automatically classify patients in the target groups of COVID-19, pneumonia, and normal, based on chest X-ray images. Our algorithm generates two complementary images from each raw image in the dataset, and only works on a 4-feature...
The dataset consists of 5000 chest X-ray image samples such as normal chest X-ray, covid19, and other pneumonia. However, the dataset is downloaded from the Github repository. The Fig. 5 shows the multi-level classification of COVID-19, normal and other pneumonia. Download: Download high-...
As in [22], we collected Normal, Bacterial Pneumonia, and non COVID-19 Viral Pneumonia chest X-ray images from the Kaggle repository ‘Chest X-ray Images (Pneumonia)’ [58], which is derived from [59]. Chest X-ray images of COVID-19 patients were obtained from the Kaggle repository ...
Build a model that can classify whether a given patient has pneumonia, given a chest x-ray image. To speed up image pre-processing, 1024x1024 images were downsized to be either 150x150 or 210x210. All images are categorized into two groups: NORMAL and PNEUMONIA. DataPneumoniaNormalSum Tr...

The main contribution of this paper is the multi-kernel-size, spatial-channel attention method (MKSC) to analyze chest X-ray images for COVID-19 detection. Our proposed method integrates a feature extraction module, a multi-kernel-size attention module, and a classification module. We use X-...

Automatic Detection of COVID-19 and Pneumonia from Chest X-Ray using Deep Learning In this study, a dataset of X-ray images from patients with common viral pneumonia, bacterial pneumonia, confirmed Covid-19 disease was utilized for the automatic detection of the Coronavirus disease. The point ...
Several challenges are faced in the segmentation of infected regions, including high variation in infection characteristics and low-intensity contrast between infections and normal tissues. In this work, we have taken the PA view of the chest X-ray images, which were found unhealthy at the time ...
