Zero-padding layer for 2D input (e.g. picture).
Inherits From: Layer
tf.keras.layers.ZeroPadding2D(
padding=(1, 1), data_format=None, **kwargs
)
This layer can add rows and columns of zeros at the top, bottom, left and right side of an image tensor.
Arguments | |
---|---|
padding
|
Int, or tuple of 2 ints, or tuple of 2 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, height, width, channels) while channels_first
corresponds to inputs with shape
(batch, channels, height, width) .
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:
4D tensor with shape:
- If
data_format
is"channels_last"
:(batch, rows, cols, channels)
- If
data_format
is"channels_first"
:(batch, channels, rows, cols)
Output shape:
4D tensor with shape:
- If
data_format
is"channels_last"
:(batch, padded_rows, padded_cols, channels)
- If
data_format
is"channels_first"
:(batch, channels, padded_rows, padded_cols)
