tf.keras.layers.Cropping2D

Cropping layer for 2D input (e.g. picture).

Inherits From: Layer, Module

tf.keras.layers.Cropping2D(
    cropping=((0, 0), (0, 0)), data_format=None, **kwargs
)

It crops along spatial dimensions, i.e. height and width.

Examples:

input_shape = (2, 28, 28, 3)
x = np.arange(np.prod(input_shape)).reshape(input_shape)
y = tf.keras.layers.Cropping2D(cropping=((2, 2), (4, 4)))(x)
print(y.shape)
(2, 24, 20, 3)

Args
`cropping`	Int, or tuple of 2 ints, or tuple of 2 tuples of 2 ints. If int: the same symmetric cropping is applied to height and width. If tuple of 2 ints: interpreted as two different symmetric cropping values for height and width: `(symmetric_height_crop, symmetric_width_crop)`. If tuple of 2 tuples of 2 ints: interpreted as `((top_crop, bottom_crop), (left_crop, right_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, height, width, channels)` while `channels_first` corresponds to inputs with shape `(batch_size, channels, height, width)`. When unspecified, uses `image_data_format` value found in your Keras config file at `~/.keras/keras.json` (if exists) else 'channels_last'. Defaults to 'channels_last'.

Args

cropping

Int, or tuple of 2 ints, or tuple of 2 tuples of 2 ints.

If int: the same symmetric cropping is applied to height and width.
If tuple of 2 ints: interpreted as two different symmetric cropping values for height and width: (symmetric_height_crop, symmetric_width_crop).
If tuple of 2 tuples of 2 ints: interpreted as ((top_crop, bottom_crop), (left_crop, right_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, height, width, channels) while channels_first corresponds to inputs with shape (batch_size, channels, height, width). When unspecified, uses image_data_format value found in your Keras config file at ~/.keras/keras.json (if exists) else 'channels_last'. Defaults to 'channels_last'.

Input shape
4D tensor with shape: If `data_format` is `"channels_last"`: `(batch_size, rows, cols, channels)` If `data_format` is `"channels_first"`: `(batch_size, channels, rows, cols)`

Input shape

4D tensor with shape:

If data_format is "channels_last": (batch_size, rows, cols, channels)
If data_format is "channels_first": (batch_size, channels, rows, cols)

Output shape
4D tensor with shape: If `data_format` is `"channels_last"`: `(batch_size, cropped_rows, cropped_cols, channels)` If `data_format` is `"channels_first"`: `(batch_size, channels, cropped_rows, cropped_cols)`

Output shape

4D tensor with shape:

If data_format is "channels_last": (batch_size, cropped_rows, cropped_cols, channels)
If data_format is "channels_first": (batch_size, channels, cropped_rows, cropped_cols)
