BatchToSpace
#include <array_ops.h>
BatchToSpace
for 4-D tensors of type T.
Summary
This is a legacy version of the more general
BatchToSpaceND
.
Rearranges (permutes) data from batch into blocks of spatial data, followed by cropping. This is the reverse transformation of SpaceToBatch. More specifically, this op outputs a copy of the input tensor where values from the
batch
dimension are moved in spatial blocks to the
height
and
width
dimensions, followed by cropping along the
height
and
width
dimensions.
Args:
-
scope: A
Scope
object
-
input: 4-D tensor with shape
[batch*block_size*block_size, height_pad/block_size, width_pad/block_size, depth]
. Note that the batch size of the input tensor must be divisible by
block_size * block_size
.
-
crops: 2-D tensor of non-negative integers with shape
[2, 2]
. It specifies how many elements to crop from the intermediate result across the spatial dimensions as follows:
crops = [[crop_top, crop_bottom], [crop_left, crop_right]]
Returns:
-
Output
: 4-D with shape
[batch, height, width, depth]
, where:
height = height_pad - crop_top - crop_bottom
width = width_pad - crop_left - crop_right
The attr
block_size
must be greater than one. It indicates the block size.
Some examples:
(1) For the following input of shape
[4, 1, 1, 1]
and block_size of 2:
[[[[1]]], [[[2]]], [[[3]]], [[[4]]]]
The output tensor has shape
[1, 2, 2, 1]
and value:
x = [[[[1], [2]], [[3], [4]]]]
(2) For the following input of shape
[4, 1, 1, 3]
and block_size of 2:
[[[[1, 2, 3]]], [[[4, 5, 6]]], [[[7, 8, 9]]], [[[10, 11, 12]]]]
The output tensor has shape
[1, 2, 2, 3]
and value:
x = [[[[1, 2, 3], [4, 5, 6]],
[[7, 8, 9], [10, 11, 12]]]]
(3) For the following input of shape
[4, 2, 2, 1]
and block_size of 2:
x = [[[[1], [3]], [[9], [11]]],
[[[2], [4]], [[10], [12]]],
[[[5], [7]], [[13], [15]]],
[[[6], [8]], [[14], [16]]]]
The output tensor has shape
[1, 4, 4, 1]
and value:
x = [[[[1], [2], [3], [4]],
[[5], [6], [7], [8]],
[[9], [10], [11], [12]],
[[13], [14], [15], [16]]]]
(4) For the following input of shape
[8, 1, 2, 1]
and block_size of 2:
x = [[[[1], [3]]], [[[9], [11]]], [[[2], [4]]], [[[10], [12]]],
[[[5], [7]]], [[[13], [15]]], [[[6], [8]]], [[[14], [16]]]]
The output tensor has shape
[2, 2, 4, 1]
and value:
x = [[[[1], [3]], [[5], [7]]],
[[[2], [4]], [[10], [12]]],
[[[5], [7]], [[13], [15]]],
[[[6], [8]], [[14], [16]]]]
