Parameters
roiWidth
Maximum width of the image, in pixels.
pBufferSize
Pointer to the size of the working buffer.
Description
This function operates with ROI (see Regions of Interest in Intel IPP ).
This function computes the size of the working buffer required for the function ippiFindPeaks3x3 . The buffer with the length
pBufferSize[0]
can be used to filter images with width that is less than or equal to
roiWidth
.
Example

shows how to use the function
ippiFindPeaks3x3GetBufferSize_32f_C1R
.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr
Indicates an error condition if the pointer
pBufferSize
is
NULL
.
ippStsSizeErr
Indicates an error condition if
roiWidth
is less than 1.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
