Interface for the kernel to run an arbitrary size convolution on a tensor.
(Currently supports 3x3, 5x5, 7x7 and 9x9). The client can supply a convolution matrix \( C_{m,n} \).
\begin{eqnarray} k_0 &=& \frac{m}{2} \\ l_0 &=& \frac{n}{2} \\ sum &=& \sum_{k=0,l=0}^{k=m-1,l=n-1} input(x+k-k_0, y+l-l_0) C_{k,l} \end{eqnarray}

The size of the border for that kernel.
Reimplemented from IKernel.
void configure | ( | const ICLTensor * | input, |
ICLTensor * | output, | ||
const int16_t * | conv, | ||
uint32_t | scale, | ||
bool | border_undefined | ||
) |
Initialise the kernel's input, output and border mode.
[in] | input | Source tensor. Data types supported: U8. |
[out] | output | Destination tensor, Data types supported: U8, S16. |
[in] | conv | Convolution matrix to apply to the input tensor. |
[in] | scale | Scale of the convolution matrix. If 0 is passed, it will be set to the sum of the coefficients of the convolution or 1 if they add up to 0. |
[in] | border_undefined | True if the border mode is undefined. False if it's replicate or constant. |
