Detailed Description

Interface for the OpenCL kernel to be used for reshaping the tensor before returning the result of deconvolution.

The input tensor to this OpenCL kernel is expected to be the result of a CLGEMM operation between the Deconvolution input and the Deconvolution filter.

The input tensor should have the following shape: [filter_width * filter_height * ofms, width, height, batch_size]

The output tensor should have the following shape: [stride_x * (input_width - 1) + filter_width - 2 * padx, stride_y * (input_height - 1) + filter_height - 2 * pady, ofms, batch_size]

For example, given a tensor with dimensions [4, 2, 2] this function returns a tensor with dimensions [1, 4, 4].

◆ run()

void run ( const Window window,
cl::CommandQueue &  queue 
)
overridevirtual

Enqueue the OpenCL kernel to process the given window on the passed OpenCL command queue.

Note
The queue is not flushed by this method, and therefore the kernel will not have been executed by the time this method returns.
Parameters
[in]windowRegion on which to execute the kernel. (Must be a valid region of the window returned by window()).
[in,out]queueCommand queue on which to enqueue the kernel.

Reimplemented from ICLKernel.
