{\bf NPP} is the package containing a set of functions focusing on
image and video processing. 
\begin{itemize}
\item NPP 1.0 works with CUDA 2.3
\item NPP 1.1 works with CUDA 3.0
\end{itemize}

With CUDA 4.0, NPP can run 10x to 36x faster in image processing. What it can
does?
\begin{enumerate}
  \item Data exchange \& initialization: Set, Convert, CopyConstBorder, Copy, 
Transpose, SwapChannels
  \item Color Conversion: RGB To YCbCr (\& vice versa), 
ColorTwist, \verb!LUT_Linear!
  \item Threshold \& Compare Ops: Threshold, Compare
  \item Statistics: Mean, StdDev, NormDiff, MinMax, 
Histogram, SqrIntegral, RectStdDev
  \item Filter Functions: FilterBox, Row, Column, Max, Min, Median, 
Dilate, Erode, SumWindowColumn/Row
  \item Geometry Transforms:
Mirror, WarpAffine / Back/ Quad, 
WarpPerspective / Back / Quad, Resize
  \item Arithmetic \& Logical Ops:
Add, Sub, Mul, Div, AbsDiff
\item JPEG:
DCTQuantInv/Fwd, Quantiza
  \item 
\end{enumerate}

CUDA 4.1 has +2000 image processing and signal processing primitives.
CUDA NPP 4.1 increases upto 40x performance than Intel
IPP.
