Parameters
- dstRoi
- Size of the destination image ROI.
- rate
- Ratio between neighbouring levels (1 <rate≤10).
- kerSize
- Size of the kernel.
- pStateSize
- Pointer to the size of the pyramid layer state structure.
Description
This function operates with ROI (see
Regions of Interest in Intel IPP
).
This function computes the size of the
pState
structure to build an upper pyramid layer and the size of the temporary buffer, in bytes. This structure is used by the
ippiPyramidLayerUp
function and can be applied to process images with size not greater than
dstRoi
. For an example on how to use this function, refer to the example provided with the
ippiPyramidLayerDown
function description.
Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error when at least one of the pointers isNULL.
- ippStsSizeErr
- Indicates an error when the width or height of images is less than, or equal to zero.
- ippStsBadArgErr
- Indicates an error whenkerSizeis even, or equal to or less than 0; or whenrateis out of the range.
