Parameters
- pSrc
- Pointer to the source image ROI.
- srcStep
- Distance, in bytes, between the starting points of consecutive lines in the source image.
- srcRoiSize
- Size of source image ROI, in pixels.
- pDst
- Pointer to the destination image ROI.
- dstStep
- Distance, in bytes, between the starting points of consecutive lines in the destination image.
- dstRoiSize
- Size of destination image ROI, in pixels.
- pState
- The pointer to the pyramid layer structure.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function creates an upper pyramid layer
pDst
from the source image pSrc
. The function performs upsampling of the source image and then applies the convolution kernel using the mirror border. Before calling the
ippiPyramidLayerUp
function, compute the size of the pyramid layer structure pState
using the PyramidLayerUpGetSize function and initialize the structure using the PyramidLayerUpInit function. The function can process images with srcRoiSize
not greater than the roiSize
parameter specified in the PyramidLayerUpInit function.This function uses the mirrored border.
Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error if one of the specified pointers isNULL.
- ippStsSizeErr
- Indicates an error condition ifsrcRoiSizeordstRoiSizehas a field with zero or negative value.
- ippStsStepErr
- Indicates an error condition ifsrcStepis less thansrcRoiSize.width*<pixelSize>, ordstStepis less thandstRoiSize.width*<pixelSize>.
- ippStsNotEvenStepErr
- Indicates an error condition if one of the step values is not divisible by 4 for floating-point images, or by 2 for short-integer images.
- ippStsBadArgErr
- Indicates an error condition ifpState->ratehas wrong value.
