Detailed Description

Enumeration Type Documentation

◆ 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

#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)

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)
