Detailed Description

Up- and Downscaling of images.

Function Documentation

IUCORE_DLLAPI void iu::prolongate	(	const iu::ImageGpu_32f_C1 *	src,
		iu::ImageGpu_32f_C1 *	dst,
		IuInterpolationType	interpolation = IU_INTERPOLATE_NEAREST
	)

Scaling the image src up to the size of dst.

Image prolongation.

Parameters

[in]	src	Source image [device]
[out]	dst	Destination image [device]
[in]	interpolation	The type of interpolation used for scaling up the image.

Note

The bcubic_bspline_prefilter yields sharper results when switched on. Note that this only works nicely with a scale_factor=0.5f.

IUCORE_DLLAPI void iu::reduce	(	const iu::ImageGpu_32f_C1 *	src,
		iu::ImageGpu_32f_C1 *	dst,
		IuInterpolationType	interpolation = IU_INTERPOLATE_LINEAR,
		bool	gauss_prefilter = true
	)

Scaling the image src down to the size of dst.

Image reduction.

Parameters

[in]	src	Source image [device]
[out]	dst	Destination image [device]
[in]	interpolation	The type of interpolation used for scaling down the image.
[in]	gauss_prefilter	Toggles gauss prefiltering. The sigma and kernel size is chosen dependent on the scale factor.

Note

The bcubic_bspline_prefilter yields sharper results when switched on. Note that this only works nicely with a scale_factor=0.5f.

IUCORE_DLLAPI void iu::remap	(	iu::ImageGpu_8u_C1 *	src,
		iu::ImageGpu_32f_C1 *	dx_map,
		iu::ImageGpu_32f_C1 *	dy_map,
		iu::ImageGpu_8u_C1 *	dst,
		IuInterpolationType	interpolation = IU_INTERPOLATE_LINEAR
	)

Remapping the image src with the given disparity fields dx, dy.

Image remapping (warping).

Parameters

[in]	src	Source image [device]
[in]	dx_map	Disparities (dense) in x direction [device]
[in]	dy_map	Disparities (dense) in y direction [device]
[out]	dst	Destination image [device]
[in]	interpolation	The type of interpolation used for scaling up the image.

Note

The bcubic_bspline_prefilter yields sharper results when switched on. Note that this only works nicely with a scale_factor=0.5f.
