The size of the border for that kernel.
Reimplemented from IKernel.
void configure | ( | const ICLTensor * | input, |
ICLTensor * | output_x, | ||
ICLTensor * | output_y, | ||
bool | border_undefined | ||
) |
Initialise the kernel's source, destination and border.
[in] | input | Source tensor. Data types supported: U8. |
[out] | output_x | (Optional) Destination tensor for the X gradient, Data types supported: S16. |
[out] | output_y | (Optional) Destination tensor for the Y gradient, Data types supported: S16. |
[in] | border_undefined | True if the border mode is undefined. False if it's replicate or constant. |
|
delete |
Prevent instances of this class from being copied (As this class contains pointers).
|
default |
Allow instances of this class to be moved.
|
overridevirtual |
Enqueue the OpenCL kernel to process the given window on the passed OpenCL command queue.
[in] | window | Region on which to execute the kernel. (Must be a valid region of the window returned by window()). |
[in,out] | queue | Command queue on which to enqueue the kernel. |
Implements ICLKernel.
