◆ af_minfilt()

AFAPI af_err af_minfilt ( af_array out,
const af_array  in,
const dim_t  wind_length,
const dim_t  wind_width,
const af_border_type  edge_pad 
)

C Interface for minimum filter.

Parameters
[out]outarray is the processed image
[in]inarray is the input image
[in]wind_lengthis the kernel height
[in]wind_widthis the kernel width
[in]edge_padvalue will decide what happens to border when running filter in their neighborhood. It takes one of the values [AF_PAD_ZERO | AF_PAD_SYM]
Returns
AF_SUCCESS if the minimum filter is applied successfully, otherwise an appropriate error code is returned.

◆ minfilt()

AFAPI array af::minfilt ( const array in,
const dim_t  wind_length = 3,
const dim_t  wind_width = 3,
const borderType  edge_pad = AF_PAD_ZERO 
)

C++ Interface for minimum filter.

Parameters
[in]inarray is the input image
[in]wind_lengthis the kernel height
[in]wind_widthis the kernel width
[in]edge_padvalue will decide what happens to border when running filter in their neighborhood. It takes one of the values [AF_PAD_ZERO | AF_PAD_SYM]
Returns
the processed image
