Detailed Description

Wrap takes an unwrapped image (see unwrap()) and converts it back to an image.

The inputs to this function should be the same as the inputs used to generate the unwrapped image.

Function Documentation

AFAPI af_err af_wrap	(	af_array *	out,
		const af_array	in,
		const dim_t	ox,
		const dim_t	oy,
		const dim_t	wx,
		const dim_t	wy,
		const dim_t	sx,
		const dim_t	sy,
		const dim_t	px,
		const dim_t	py,
		const bool	is_column
	)

C Interface wrapper for wrap.

Parameters

[out]	out	is an array after converting
[in]	in	is the input array
[in]	ox	is the 0th-dimension of out
[in]	oy	is the ist-dimension of out
[in]	wx	is the block window size along 0th-dimension between
[in]	wy	is the block window size along 1st-dimension between
[in]	sx	is the stride along 0th-dimension
[in]	sy	is the stride along 1st-dimension
[in]	px	is the padding used along 0th-dimension between [0, wx).
[in]	py	is the padding used along 1st-dimension between [0, wy).
[in]	is_column	specifies the layout for the unwrapped patch. If is_column is false, the rows are treated as the patches

Returns

AF_SUCCESS if the color transformation is successful, otherwise an appropriate error code is returned.

Note

The padding used in af_unwrap is calculated from the provided parameters

AFAPI array af::wrap	(	const array &	in,
		const dim_t	ox,

		const dim_t	wx,
		const dim_t	wy,
		const dim_t	sx,
		const dim_t	sy,
		const dim_t	px = 0,

		const bool	is_column = true
	)

C++ Interface wrapper for wrap.

Parameters

[in]	in	is the input image (or set of images)
[in]	ox	is the 0th-dimension of output
[in]	oy	is the ist-dimension of output
[in]	wx	is the block window size along 0th-dimension between
[in]	wy	is the block window size along 1st-dimension between
[in]	sx	is the stride along 0th-dimension
[in]	sy	is the stride along 1st-dimension
[in]	px	is the padding used along 0th-dimension between [0, wx).
[in]	py	is the padding used along 1st-dimension between [0, wy).
[in]	is_column	specifies the layout for the unwrapped patch. If is_column is false, the rows are treated as patches

Returns

an array of images after converting rows or columns into image windows
