Enumeration Type Documentation

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

Definition at line 91 of file NPP_staging.hpp.

Filter types for image resizing.

Enumerator
nppStSupersample 

Supersampling. For downscaling only.

nppStBicubic 

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

Definition at line 103 of file 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)
