Gabor Dictionary of Sparse Image Patches Selected in Prior Boundaries for 3D Liver Segmentation in CT Images

Figure 8

Results of the liver boundary point set obtained by the sparse dictionary method. (A1)∼(A3) and (B1)∼(B3) offer two sets of segmentation results, respectively. Columns 1–3 show the cross-sectional, sagittal, and coronal planes of the same data, respectively. (a1)∼(a3) are the locally amplified views corresponding to the green boxes in (A1)∼(A3), respectively.
