Description |
|---|---|---|
|
hrPrev |
HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) | |
|
ipImage |
Source image (1 channel, USINT elements) | |
|
ipActiveContour |
Initial contour, which will be adjusted | |
|
fAlpha |
float |
Continuity energy coefficient |
|
fBeta |
float |
Curvature energy coefficient |
|
fGamma |
float |
Image energy coefficient |
|
nWindowWidth |
ULONG |
Window width (3, 5, 7, ...) |
|
nWindowHeight |
ULONG |
Window height (3, 5, 7, ...) |
|
nMaxIterations |
ULONG |
Maximum iterations |
|
bUseGradient |
bool |
If true, the gradient magnitude is used as image energy (otherwise: pixel intensity) |
