Detailed Description

Basic function to execute non linear filter.

This function calls the following NEON kernels:

  1. NEFillBorderKernel (executed if border_mode == CONSTANT or border_mode == REPLICATE)
  2. NENonLinearFilterKernel
Note
Supported mask dimensions squares of sizes 3, 5

◆ configure()

void configure ( ITensor input,
ITensor output,
NonLinearFilterFunction  function,
unsigned int  mask_size,
MatrixPattern  pattern,
const uint8_t *  mask,
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 type supported: U8
[in]functionNon linear function to perform
[in]mask_sizeMask size. Supported sizes: 3, 5
[in]patternMask pattern
[in]maskThe given mask. Will be used only if pattern is specified to PATTERN_OTHER
[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.
