Parameters
pSrc |
Pointer to the source image ROI. |
srcStep |
Distance in bytes between starts of consecutive lines in the source image. |
pDst |
Pointer to the destination image ROI. |
dstStep |
Distance in bytes between starts 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 starts of consecutive lines in the source and destination image for the in-place operation. |
roiSize |
Size of the source and destination ROI in pixels. |
Description
The functions ippiWinBartlett and ippiWinBartlettSep are declared in the ippi.h file. It operates with ROI (see Regions of Interest in Intel IPP).
These functions compute the Bartlett (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 Bartlett window function for one-dimensional case with M elements
is defined as follows:
The ippiWinBartlettSep 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 condition if pSrc or pDst pointer is NULL. |
ippStsStepErr |
Indicates an error condition if srcStep or dstStep value is zero or negative. |
ippStsSizeErr |
Indicates an error condition if width or height of images is less than or equal to zero. |
