DICOM images. image-processing tasks, such as pattern recognition, object detection, segmentation, etc. Almost all the literature on nodule detection and almost all tutorials on the forums advised to first segment out the lung tissue from the CT-scans. In the LUng Nodule Analysis 2016 (LUNA16) challenge [9], such ground-truth was provided based on CT scans from the Lung Image Database Consortium and Im- End-to-End Lung Nodule Segmentation and Visualization in Computed Tomography using Attention U-Net. In general, a lung region segmentation method contains the following main steps: (a) thresholding-based binarization, … In this paper, we challenge the basic assumption that a Curve parameter discretization? Lung CT image segmentation is a necessary initial step for lung image analysis, it is a prerequisite step to provide an accurate lung CT image analysis such as lung cancer detection. J. Digit.
