Parameters
roiSize
Maximum image size (in pixels).
pBufferSize
Pointer to the computed size of the 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 ippiFastMarching function. The buffer with the length
pBufferSize
[0]
can be used to filter images with width that is equal to or less than the parameter
roiSize
specified for the function
ippiFastMarching
.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr
Indicates an error condition if
pBufferSize
pointer is
NULL
.
ippStsSizeErr
Indicates an error condition if
roiSize
is lessthan 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.
