Detailed Description

Basic function to execute convolution of size 3x3.

This function calls the following Neon kernels:

  1. NEFillBorderKernel (executed if border_mode == CONSTANT or border_mode == REPLICATE)
  2. NEConvolution3x3Kernel
Deprecated:
This function is deprecated and is intended to be removed in 21.05 release

Member Function Documentation

◆ configure()

void configure ( ITensor input,
ITensor output,
const int16_t *  conv,
uint32_t  scale,
BorderMode  border_mode,
uint8_t  constant_border_value = 0 
)

Initialize the function's source, destination, conv and border_mode.

Parameters
[in,out]inputSource tensor. Data type supported: U8. (Written to only for border_mode != UNDEFINED)
[out]outputDestination tensor, Data types supported: U8/S16.
[in]convMatrix_size x matrix_size S16 coefficients structured as a row-major 2D array in a linear buffer.
[in]scaleScale 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_modeStrategy to use for borders.
[in]constant_border_value(Optional) Constant value to use for borders if border_mode is set to CONSTANT.
