Parameters
pSrc0 |
Pointer to the source image row #0. |
pSrc1 |
Pointer to the source image row #1. |
pSrc2 |
Pointer to the source image row #2. |
pSrcHigh0 |
Pointer to the high frequency component row #0 of a source image. |
pDstLow0 |
Pointer to the low frequency component row #0 of a destination image. |
pDstHigh1 |
Pointer to the high frequency component row #1 of a destination image. |
width |
Width in pixels of rows. |
Description
The function ippiWTFwdColLift_B53_JPEG2K is declared in the ippj.h file. This function performs a single step of row-scan-based wavelet decomposition of the source image columns using the 5-3 reversible filter.
For each i-pixel in the row, this function
computes the following
values:
Here the notation
designates
the floor function, that is, the largest integer not exceeding
x.
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error condition if one of the specified pointers is NULL. |
ippStsSizeErr |
Indicates an error condition if the width of row has zero or negative value. |
