abstract = "The purpose of this work is to propose two new automatic
segmentation methods in CT images: one for the lungs and one for
their lesions. The lung segmentation method uses morphological
filters and the max-tree, a data structure that represents an
image through its connected components. Results show that the
method presented a good performance when compared to the manual
segmentation and it was able to not exclude lesions located in the
borders in most of the images, which is challenging when the
lesions are small and disconnected located in this region. This
method obtained an average Dice of 98%. The lesion segmentation
method uses the image with the segmented lungs to calculate the
features to train a classifier that distinguishes between normal
tissue and abnormal tissue (which contains lesions). This method
also presented good results as it turned out not being very
sensible to parameters' choice and it obtained an average Dice of
62% for the slices with severe pathologies.",
