Comparing Inclusion Methods on Juxta-pleural into Lung Parenchyma

Résumé fourni par la source

Before lung cancer classification, the preprocessing work can include lung segmentation for separating the lung area from the rest; however, there are nodule conditions called juxta-pleural and pleural-tail nodules that grow on or connect to the pleural wall. These types of nodules will get excluded during lung segmentation using standard thresholding; thus, an additional method is needed to prevent this exclusion and get the nodule included within lung parenchyma. There are two known methods for addressing the juxta-pleural nodule to be included in lung parenchyma during segmentation: the Freeman Chain Code and Morphological operation. Each technique has advantages and disadvantages; Morphological Operation excels in speed but cannot address large juxta-pleural openings. 2D Chain Code can address larger juxta-pleural but fails to correct segment separation; 3D Chain Code can address most juxta-pleural but runs slowly.
