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.
- threshold
- Threshold level value.
- roiSize
- Size of the source and destination image ROI.
Description
This function operates with ROI (see Regions of Interest in Intel
IPP). This function performs deinterlacing of a two-field image, pointed to
by
pSrc
, using content
adaptive vertical temporal (CAVT) filtering. The field pointed to by
pSrc
is copied to pDst
, while the other field in
the destination image, pointed to by pDst
+dstStep
, is the interpolated
one. Note that you can set the pointers to the bottom left corner of the images and
use negative steps to have the bottom field unchanged and the top one
interpolated.The
threshold
parameter is the edge detection threshold with the valid
range [0-2041] regulating the probability of temporal interpolation: 0 means that
all the pixels are interpolated only spatially, from the vertically neighbouring
pixels of the copied field, 2041 - that combined spatial-temporal interpolation,
involving the pixels from the modified field as well, is applied to all the
pixels.Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error.
- ippStsNullPtrErr
- Indicates an error condition if one of the specified pointers isNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSize.widthis less than or equal to 0, orroiSize.heightis odd or less than 8.
