“…Some works [ 8 , 9 , 10 , 11 ] used different algorithms for lung reconstruction, among those options some use filling holes algorithm, morphology to define the lungs perimeter or connectivity to reconstruct the lungs volume and verify it as a solid one. Also there are other studies [ 10 , 12 ] with the main task in the threshold decision, the option of this methodology is an adaptive or a minimum error threshold which decides a parameter for lung extraction. The combination of both methods to develop a robust lung extraction represents a significant step for our algorithm of lung nodule detection.…”

“…A vast amount of 3D algorithms were proposed targeting spherical volumes mostly because of the similarity to nodules [ 8 , 10 ]. There were also other algorithms focusing in the width of the structures in order to differentiate between tubes and round objects [ 9 , 11 , 12 , 13 , 14 ]. 3D methods require greater processing time and find a noticeable amount of FPs per scan leading towards more demanding classification characteristics.…”

“…In lung cancer CAD systems, lung nodule detection methods can be categorized into three main categories [ 5 ]: template-based [ 6 8 ], segmentation-based [ 9 11 ], and classification-based [ 12 15 ]. Among the reported existing work, the systems that included a classification component in their structure have performed better than their counterparts.…”

“…In the above methods, the multilevel threshold based approaches [2][3][4][5][16][17][18][19][20] usually get better performances than active contour algorithm [6] and supervised voxel classification methods [7]. Equally, it has an obvious disadvantage for segmenting the fuzzy lesion which tends to be the probable modality of malignant nodule such as GGO (Ground Glass Opacity).…”

“…Many methods for the lung parenchyma and pulmonary nodules detection have been studied, such as threshold rule based conversion methods [16][17][18][19][20], morphology algorithm [21], genetic algorithm, model based methods [22][23][24], classifier based methods [25] and the enhanced filtering methods [26][27][28]. Li et al use an improved CV Level-Set algorithm for segmenting lung nodules based on SVM (support vector machine) classifier [25].…”
