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 theippiWinHammingGetBufferSizeorippiWinHammingSepGetBufferSizefunction.
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 whenpSrcorpDstpointer isNULL.
- ippStsStepErr
- Indicates an error whensrcStepordstStepvalue is zero or negative.
- ippStsSizeErr
- Indicates an error when width or height of images is less than, or equal to zero.
