`tf.compat.v1.keras.layers.Cropping3D`
tf.keras.layers.Cropping3D(
cropping=((1, 1), (1, 1), (1, 1)), data_format=None, **kwargs
)
Examples:
input_shape = (2, 28, 28, 10, 3)
x = np.arange(np.prod(input_shape)).reshape(input_shape)
y = tf.keras.layers.Cropping3D(cropping=(2, 4, 2))(x)
print(y.shape)
(2, 24, 20, 6, 3)
Args |
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_size, spatial_dim1, spatial_dim2, spatial_dim3, channels)
while channels_first corresponds to inputs with shape
(batch_size, 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".

5D tensor with shape:
- If
data_format is "channels_last" :
(batch_size, first_axis_to_crop, second_axis_to_crop,
third_axis_to_crop, depth)
- If
data_format is "channels_first" :
(batch_size, 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_size, first_cropped_axis, second_cropped_axis,
third_cropped_axis, depth)
- If
data_format is "channels_first" :
(batch_size, depth, first_cropped_axis, second_cropped_axis,
third_cropped_axis)
