Segmentation of Tumour region in Lung CT Images, is the initial task of the 2018 VIP-Cup challenge. Segmentation (i.e., providing contour or bounding box) and Localization (i.e., a class label is supposed to be assigned to each pixel) are considered as
the critical step within the Radiomics workflow, as typically Radiomics features are extracted from segmented sections. Although, manual delineation of the gross tumour is the conventional
(standard) clinical approach, it is time consuming and extensively sensitive to inter-observer variability. Automatic and semi-automatic segmentation methods together with their ability to minimize manual
error and increase consistency of delineating regions are of paramount importance.
