tf.keras.layers.Cropping3D(
    cropping=((1, 1), (1, 1), (1, 1)), data_format=None, **kwargs
)

Arguments
cropping	Int, or tuple of 3 ints, or tuple of 3 tuples of 2 ints. If int: the same symmetric cropping is applied to depth, height, and width. If tuple of 3 ints: interpreted as two different symmetric cropping values for depth, height, and width:(symmetric_dim1_crop, symmetric_dim2_crop, symmetric_dim3_crop). If tuple of 3 tuples of 2 ints: interpreted as((left_dim1_crop, right_dim1_crop), (left_dim2_crop, right_dim2_crop), (left_dim3_crop, right_dim3_crop))
data_format	A string, one of channels_last (default) or channels_first. The ordering of the dimensions in the inputs.channels_last corresponds to inputs with shape(batch, spatial_dim1, spatial_dim2, spatial_dim3, channels)while channels_first corresponds to inputs with shape(batch, channels, spatial_dim1, spatial_dim2, spatial_dim3). It defaults to the image_data_format value found in your Keras config file at ~/.keras/keras.json. If you never set it, then it will be "channels_last".

Arguments

cropping

Int, or tuple of 3 ints, or tuple of 3 tuples of 2 ints. If int: the same symmetric cropping is applied to depth, height, and width. If tuple of 3 ints: interpreted as two different symmetric cropping values for depth, height, and width:(symmetric_dim1_crop, symmetric_dim2_crop, symmetric_dim3_crop). If tuple of 3 tuples of 2 ints: interpreted as((left_dim1_crop, right_dim1_crop), (left_dim2_crop, right_dim2_crop), (left_dim3_crop, right_dim3_crop))

data_format

A string, one of channels_last (default) or channels_first. The ordering of the dimensions in the inputs.channels_last corresponds to inputs with shape(batch, spatial_dim1, spatial_dim2, spatial_dim3, channels)while channels_first corresponds to inputs with shape(batch, channels, spatial_dim1, spatial_dim2, spatial_dim3). It defaults to the image_data_format value found in your Keras config file at ~/.keras/keras.json. If you never set it, then it will be "channels_last".

Input shape:

5D tensor with shape:

If data_format is "channels_last":(batch, first_axis_to_crop, second_axis_to_crop, third_axis_to_crop, depth)
If data_format is "channels_first":(batch, depth, first_axis_to_crop, second_axis_to_crop, third_axis_to_crop)

Output shape:

5D tensor with shape:

If data_format is "channels_last":(batch, first_cropped_axis, second_cropped_axis, third_cropped_axis, depth)
If data_format is "channels_first":(batch, depth, first_cropped_axis, second_cropped_axis, third_cropped_axis)
