Function Documentation

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]	out	array is the processed image
[in]	in	array is the input image
[in]	wind_length	is the kernel height
[in]	wind_width	is the kernel width
[in]	edge_pad	value 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.

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]	in	array is the input image
[in]	wind_length	is the kernel height
[in]	wind_width	is the kernel width
[in]	edge_pad	value 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
