Lung cancer has become one of the most significant diseases in human history. The World Health Organization estimates the worldwide death toll from lung cancer will be 10,000,000 by 2030. The accuracy of detecting tumor shape and location plays a vital role in successfully diagnosing and treating tumors. Computed tomography (CT) is one of the most common imaging modalities for examining and screening lung cancer. Segmentation of pulmonary nodules remains a challenging task due to intrinsic noise, low contrast, intensity-profile inhomogeneity, and variable sizes and shapes. A common approach to delineating tumors from CT scans involves radiologists manually drawing the tumor boundary. In most cases, manual segmentation is time-consuming and prone to intra- and inter-observer variability, thus making the results unreliable. Thus, an automatic and accurate lung tumor segmentation algorithm is required to display clear boundaries of lung nodules and aid radiologists in deciding on the malignancy of these nodules. Therefore, this research proposes a novel unsupervised algorithm using superpixel-based hierarchical clustering with multilevel thresholding for segmenting lung nodules from lung CT scan images. Preliminary results indicate that the proposed model can segment lung nodules without supervision.
