From: GPU-accelerated lung CT segmentation based on level sets and texture analysis
Visualisation of the initial active surface regions: the resulting regions from (a) upper, (b) middle, and (c) lower right lung lobes. Visual comparison of the results on LCTSC Train-S1-001 set obtained with: (d) 2D active contour, and (e) 3D active surface from the proposed method.
