Description |
|---|---|---|---|
|
hrPrev |
|
HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) | |
|
ipSrcImage |
|
Source image | |
|
ipDestImage |
|
Destination image (An appropriate destination image will be created if required.) | |
|
eDestDepth |
|
Destination image depth | |
|
nKernelSize |
ULONG |
1 |
Aperture size used to compute the second-derivative filters (1, 3, 5, ..., 31) |
|
fScale |
double |
1 |
Scale factor for the computed derivative values |
|
fDelta |
double |
0 |
