Struct PaddingLayerParams 

pub struct PaddingLayerParams {
    pub padding_amounts: Option<BorderAmounts>,
    pub padding_type: Option<PaddingType>,
}

A layer that performs padding along spatial dimensions.

.. code::

  y = PaddingLayer(x)

Requires 1 input and produces 1 output.

Input A blob with rank at least 2. e.g.: blob with shape \[H_in, W_in\]. For ranks greater than 2, the leading dimensions, starting from 0 to -4 (inclusive), are all treated as batch i.e. Padding is applied on last two dimensions.

Output Same rank as the input. e.g.: blob with shape \[H_out, W_out\].

Output dimensions are calculated as follows:

.. code::

 H_out = H_in + topPaddingAmount + bottomPaddingAmount
 W_out = W_in + leftPaddingAmount + rightPaddingAmount

 topPaddingAmount == Height startEdgeSize == borderAmounts\[0\].startEdgeSize
 bottomPaddingAmount == Height endEdgeSize == borderAmounts\[0\].endEdgeSize
 leftPaddingAmount == Width startEdgeSize == borderAmounts\[1\].startEdgeSize
 rightPaddingAmount == Width endEdgeSize == borderAmounts\[1\].endEdgeSize

There are three types of padding:

• PaddingConstant, which fills a constant value at the border.
• PaddingReflection, which reflects the values at the border.
• PaddingReplication, which replicates the values at the border.

Given the following input:

.. code::

 \[1, 3, 4\]  :  1   2   3   4
               5   6   7   8
               9   10  11  12

Here is the output of applying the padding (top=2, left=2, bottom=0, right=0) with each of the supported types:

• PaddingConstant (value = 0): .. code::

   \[1, 5, 6\]  :  0   0   0  0   0   0
                 0   0   0  0   0   0
                 0   0   1  2   3   4
                 0   0   5  6   7   8
                 0   0   9  10  11  12

• PaddingReflection: .. code::

   \[1, 5, 6\]  :  11  10  9  10  11  12
                 7   6   5  6   7   8
                 3   2   1  2   3   4
                 7   6   5  6   7   8
                 11  10  9  10  11  12

• PaddingReplication: .. code::

   \[1, 5, 6\]  :  1   1   1  2   3   4
                 1   1   1  2   3   4
                 1   1   1  2   3   4
                 5   5   5  6   7   8
                 9   9   9  10  11  12

Fields

padding_amounts: Option<BorderAmounts>

Amounts to be padded to the input.

Trait Implementations

impl Clone for PaddingLayerParams

fn clone(&self) -> PaddingLayerParams

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PaddingLayerParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PaddingLayerParams

fn default() -> Self

Returns the “default value” for a type.

impl Message for PaddingLayerParams

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

impl PartialEq for PaddingLayerParams

fn eq(&self, other: &PaddingLayerParams) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
