In collaboration with Idorsia, we propose a project for idiopathic pulmonary fibrosis segmentation. Based on an image data set (see Memo0001), where each image is assigned with a progression stage label (0-5), the relevant regions which are responsible for the specific fibrosis stage should be highlighted. Special attention should be given to collagen accumulations in non-dense tissue which might serve as a biomarker for early fibroris detection.
