Mean
Statistical Operations

Primitives for computing the arithmetic mean of all the pixel values in an image. More...

Mean

Given an image $pSrc$ with width $W$ and height $H$, the arithmetic mean will be computed as

\[Mean = \frac{1}{W\cdot H}\sum_{j=0}^{H-1}\sum_{i=0}^{W-1}pSrc(j,i)\]

The mean functions require additional scratch buffer for computations.

Common parameters for nppiMean functions include:

Parameters
pSrc Source-Image Pointer.
nSrcStep Source-Image Line Step.
oSizeROI Region-of-Interest (ROI).
pMask Mask-Image Pointer.
nMaskStep Mask-Image Line Step.
nCOI Channel_of_Interest Number.
pDeviceBuffer Pointer to the required device memory allocation, Scratch Buffer and Host Pointer Use nppiMeanGetBufferHostSize_XX_XXX to determine the minium number of bytes required.
pMean Pointer to the computed mean result.
nppStreamCtx Application Managed Stream Context.
Returns
Image Data Related Error Codes, ROI Related Error Codes, or NPP_COI_ERROR if an invalid channel of interest is specified.s
