Table 2 The assessment of patch size through the segmentation characteristics and time consumption

From: Segmentation of lung parenchyma in CT images using CNN trained with the clustering algorithm generated dataset

Patch Size Time consumption for one patient Characteristics of patch segmentation Assessment
64 × 64 0.9306 s Too rough, fast Not considered
32 × 32 1.2909 s Rough, fast Bad choice
16 × 16 2.6340 s Including other tissues such as fat, tumor and heart Bad choice
4 × 4 25.8358 s Exquisite, but computationally expensive Second choice
2 × 2 98.0321 s Very exquisite, but computationally expensive Bad choice
8 × 8 7.5695 s Exquisite Best choice
