Detailed Description

Enumeration Type Documentation

enum NppStBorderType

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

enum NppStInterpMode

Filter types for image resizing

Enumerator
nppStSupersample	Supersampling. For downscaling only.
nppStBicubic	Bicubic convolution filter, a = -0.5 (cubic Hermite spline)

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

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