* ## DepthToSpace
|
|
*
|
|
* DepthToSpace rearranges (permutes) data from depth into blocks of spatial data.
|
|
* This is the reverse transformation of SpaceToDepth.
|
|
*
|
|
* Chunks of data of size block_size * block_size from depth are rearranged into
|
|
* non-overlapping blocks of size block_size x block_size.
|
|
*
|
|
* The width of the output tensor is input_depth * block_size, whereas the height
|
|
* is input_height * block_size. The depth of the input tensor must be divisible
|
|
* by block_size * block_size
|
|
*
|
|
* - crop : corp the output tensor for ROI usage.
