Parameters
pSrcLow0 |
Pointer to the source low frequency component row #0. |
pSrcHigh0 |
Pointer to the source high frequency component row #0. |
pSrcHigh1 |
Pointer to the source high frequency component row #1. |
pSrc0 |
Pointer to the reconstructed image row #0. |

Description
The function ippiWTInvColLift_B53_JPEG2K is declared in the ippj.h file. This function performs a single step of row-scan-based wavelet reconstruction 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 is less than or equal to 0. |
