Parameters
pSrc
Pointer to the source image ROI.
srcStep
Distance, in bytes, between the starting points of consecutive lines in the source image.
pDst
Pointer to the destination image ROI.
dstStep
Distance, in bytes, between the starting points of consecutive lines in the destination image.
pSrcDst
Pointer to the source and destination image ROI for the in-place operation.
srcDstStep
Distance, in bytes, between the starting points of consecutive lines in the source and destination image for the in-place operation.
roiSize
Size of the source and destination ROI, in pixels.
pBuffer
Pointer to the work buffer. To compute the size of the buffer, use the
ippiWinHammingGetBufferSize
or
ippiWinHammingSepGetBufferSize
function.
Description
These functions operate with ROI (see Regions of Interest in Intel IPP).
These functions compute the Hamming (triangle) window samples, multiply pixel values of the source image
pSrc
(
pSrcDst
for in-place flavors) with these samples, and store results in the destination image
pDst
(
pSrcDst
for in-place flavors).
The Hamming window function for one-dimensional case with
M
elements is defined as follows:
The
ippiWinHammingSep
flavor applies the window function successively to the rows and then to the columns of the image.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr
Indicates an error when
pSrc
or
pDst
pointer is
NULL
.
ippStsStepErr
Indicates an error when
srcStep
or
dstStep
value is zero or negative.
ippStsSizeErr
Indicates an error when width or height of images is less than, or equal to zero.
