class niftynet.network.highres3dnet.HighResBlock(n_output_chns, kernels=(3, 3), acti_func='relu', w_initializer=None, w_regularizer=None, with_res=True, name='HighResBlock')

Bases: niftynet.layer.base_layer.TrainableLayer

This class define a high-resolution block with residual connections kernels - specify kernel sizes of each convolutional layer

• e.g.: kernels=(5, 5, 5) indicate three conv layers of kernel_size 5

with_res - whether to add residual connections to bypass the conv layers
