Cropping layer for 3D data (e.g. spatial or spatio-temporal).
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)
Arguments | |
---|---|
cropping | Int, or tuple of 3 ints, or tuple of 3 tuples of 2 ints.
|
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:
data_format
is "channels_last"
: (batch_size, first_axis_to_crop, second_axis_to_crop, third_axis_to_crop, depth)
data_format
is "channels_first"
: (batch_size, depth, first_axis_to_crop, second_axis_to_crop, third_axis_to_crop)
5D tensor with shape:
data_format
is "channels_last"
: (batch_size, first_cropped_axis, second_cropped_axis, third_cropped_axis, depth)
data_format
is "channels_first"
: (batch_size, depth, first_cropped_axis, second_cropped_axis, third_cropped_axis)
