Edge detection is an effective method for image segmentation and feature extraction. Therefore, extracting weak edges with the inhomogeneous gray of Corona Virus Disease 2019 (COVID-19) CT images is extremely important. Multiscale morphology has been widely used in the edge detection of medical images due to its excellent boundary detection accuracy. In this paper, we propose a weak edge detection method based on Gaussian filtering and single-scale Retinex (GF_SSR), and improved multiscale morphology and adaptive threshold binarization (IMSM_ATB). As all the CT images have noise, we propose to remove image noise by Gaussian filtering. The edge of CT images is enhanced using the SSR algorithm. In addition, based on the extracted edge of CT images using improved Multiscale morphology, a particle swarm optimization (PSO) algorithm is introduced to binarize the image by automatically getting the optimal threshold. To evaluate our method, we use images from three datasets, namely COVID-19, Kaggle-COVID-19, and COVID-Chestxray, respectively. The average values of results are worthy of reference, with the Shannon information entropy of 1.8539, the Precision of 0.9992, the Recall of 0.8224, the F-Score of 1.9158, running time of 11.3000. Finally, three types of lesion images in the COVID-19 dataset are selected to evaluate the visual effects of the proposed algorithm. Compared with the other four algorithms, the proposed algorithm effectively detects the weak edge of the lesion and provides help for image segmentation and feature extraction. © 2022 Tech Science Press.

边缘检测是图像分割和特征提取的有效方法。因此，利用非均匀灰度提取冠状病毒病(COVID-19) CT图像的弱边缘是非常重要的。多尺度形态学以其优异的边界检测精度在医学图像边缘检测中得到了广泛的应用。本文提出了一种基于高斯滤波和单尺度Retinex (GF_SSR)以及改进的多尺度形态学和自适应阈值二值化(IMSM_ATB)的弱边缘检测方法。由于CT图像都存在噪声，我们提出用高斯滤波方法去除图像噪声。利用SSR算法增强了CT图像的边缘。此外，基于改进的多尺度形态学提取的CT图像边缘，引入粒子群优化(PSO)算法，通过自动获取最优阈值对图像进行二值化处理。为了评估我们的方法，我们使用了来自三个数据集的图像，分别是COVID-19、Kaggle-COVID-19和COVID-Chestxray。结果的平均值值得参考，Shannon信息熵为1.8539,Precision为0.9992,Recall为0.8224,F-Score为1.9158，运行时间为11.3000。最后，选择COVID-19数据集中的三种类型的病变图像来评估所提出算法的视觉效果。与其他四种算法相比，本文算法有效地检测了病灶的弱边缘，为图像分割和特征提取提供了帮助。©2022科技科学出版社。版权所有。
