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 is NULL.
ippStsSizeErr	Indicates an error condition if roiSize.width is less than or equal to 0, or roiSize.height is odd or less than 8.
