Description of the subsequent steps of the CIRCA algorithm. (a) Lung region segmentation includes image pre-processing and deep learning-based segmentation. As a result, a lung mask is obtained. (b) The image classification procedure includes region-of-interest (ROI) definition, calculation of radiomic features, and classification using two models: radiomic-based and image-based. As a result, class prediction with class probability is given along with the estimated class subtype.
