tensorflow::ops::Dilation2D
#include <nn_ops.h>
Computes the grayscale dilation of 4-D input and 3-D filter tensors.
Summary
The input tensor has shape [batch, in_height, in_width, depth] and the filter tensor has shape [filter_height, filter_width, depth], i.e., each input channel is processed independently of the others with its own structuring function. The output tensor has shape [batch, out_height, out_width, depth]. The spatial dimensions of the output tensor depend on the padding algorithm. We currently only support the default "NHWC" data_format.
In detail, the grayscale morphological 2-D dilation is the max-sum correlation (for consistency with conv2d, we use unmirrored filters):
output[b, y, x, c] =
max_{dy, dx} input[b,
strides[1] * y + rates[1] * dy,
strides[2] * x + rates[2] * dx,
c] +
filter[dy, dx, c]
Max-pooling is a special case when the filter has size equal to the pooling kernel size and contains all zeros.
Note on duality: The dilation of input by the filter is equal to the negation of the erosion of -input by the reflected filter.
Arguments:
- scope: A Scope object
- input: 4-D with shape
[batch, in_height, in_width, depth].
- filter: 3-D with shape
[filter_height, filter_width, depth].
- strides: The stride of the sliding window for each dimension of the input tensor. Must be:
[1, stride_height, stride_width, 1].
- rates: The input stride for atrous morphological dilation. Must be:
[1, rate_height, rate_width, 1].
- padding: The type of padding algorithm to use.
Returns:
Output: 4-D with shape [batch, out_height, out_width, depth].
