Enumeration Type Documentation#

NppStBorderType#

enum NppStBorderType

#include <opencv2/cudalegacy/NPP_staging.hpp>

Border type

Filtering operations assume that each pixel has a neighborhood of pixels. The following structure describes possible ways to define non-existent pixels.

Enumerator:

nppStBorderNone

There is no need to define additional pixels, image is extended already.

nppStBorderClamp

Clamp out of range position to borders.

nppStBorderWrap

Wrap out of range position. Image becomes periodic.

nppStBorderMirror

reflect out of range position across borders

NppStInterpMode#

enum NppStInterpMode

#include <opencv2/cudalegacy/NPP_staging.hpp>

Filter types for image resizing

Enumerator:

nppStSupersample

Supersampling. For downscaling only.

nppStBicubic

Bicubic convolution filter, a = -0.5 (cubic Hermite spline)

#include <opencv2/cudalegacy/NPP_staging.hpp>

Warp image using provided 2D vector field and 1x1 point spread function. 32-bit floating point image, single channel

During warping pixels from the source image may fall between pixels of the destination image. PSF (point spread function) describes how the source image pixel affects pixels of the destination. For 1x1 PSF only single pixel with the largest intersection is affected (similar to nearest interpolation).

Destination image size and line step must be the same as the source image size and line step

Parameters

  • pSrc — [IN] Source image pointer (CUDA device memory)

  • srcSize — [IN] Source image size

  • nSrcStep — [IN] Source image line step

  • pU — [IN] Pointer to horizontal displacement field (CUDA device memory)

  • pV — [IN] Pointer to vertical displacement field (CUDA device memory)

  • nVFStep — [IN] Displacement field line step

  • timeScale — [IN] Value by which displacement field will be scaled for warping

  • pDst — [OUT] Destination image pointer (CUDA device memory)

Returns

NCV status code

#include <opencv2/cudalegacy/NPP_staging.hpp>

Warp image using provided 2D vector field and 2x2 point spread function. 32-bit floating point image, single channel

During warping pixels from the source image may fall between pixels of the destination image. PSF (point spread function) describes how the source image pixel affects pixels of the destination. For 2x2 PSF all four intersected pixels will be affected.

Destination image size and line step must be the same as the source image size and line step

Parameters

  • pSrc — [IN] Source image pointer (CUDA device memory)

  • srcSize — [IN] Source image size

  • nSrcStep — [IN] Source image line step

  • pU — [IN] Pointer to horizontal displacement field (CUDA device memory)

  • pV — [IN] Pointer to vertical displacement field (CUDA device memory)

  • nVFStep — [IN] Displacement field line step

  • pBuffer

  • timeScale — [IN] Value by which displacement field will be scaled for warping

  • pDst — [OUT] Destination image pointer (CUDA device memory)

Returns

NCV status code

#include <opencv2/cudalegacy/NPP_staging.hpp>

Size of buffer required for vector image warping.

Parameters

  • srcSize — [IN] Source image size

  • nSrcStep — [IN] Source image line step

  • hpSize — [OUT] Where to store computed size (host memory)

Returns
