tensorflow::ops::ExtractImagePatches
#include <array_ops.h>
Extract patches
from images
and put them in the "depth" output dimension.
Summary
Arguments:
- scope: A Scope object
- images: 4-D Tensor with shape
[batch, in_rows, in_cols, depth]
. - ksizes: The size of the sliding window for each dimension of
images
. - strides: How far the centers of two consecutive patches are in the images. Must be:
[1, stride_rows, stride_cols, 1]
. - rates: Must be:
[1, rate_rows, rate_cols, 1]
. This is the input stride, specifying how far two consecutive patch samples are in the input. Equivalent to extracting patches withpatch_sizes_eff = patch_sizes + (patch_sizes - 1) * (rates - 1)
, followed by subsampling them spatially by a factor ofrates
. This is equivalent torate
in dilated (a.k.a. Atrous) convolutions. - padding: The type of padding algorithm to use.
Returns:
-
Output
: 4-D Tensor with shape[batch, out_rows, out_cols, ksize_rows * ksize_cols * depth]
containing image patches with sizeksize_rows x ksize_cols x depth
vectorized in the "depth" dimension. Noteout_rows
andout_cols
are the dimensions of the output patches.
