about the ResNet to get "coarse" livermask

[lancexiang]

Hi, about the livermask, there're some question: Judging by checking the *-ori.nii data, i find the livermask has little false positiver in view of liver slice, which is pretty good! So what i want to ask for is that how bigger is the "simple ResNet" to get this? like resnet18 such small or resnet101 such big?And i think there should be a little preprocess to get the "coarse" livermask? Hope to get a reply...
