|---|---|---|
|
hrPrev |
HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) | |
|
ipImage |
Source image (1 channel, USINT) | |
|
ipFeatures |
Returns the computed Haralick features (CTcVnContainer_Vector_LREAL). The returned feature set contains the mean and standard deviation for each of the first 13 Haralick features, computed for 0, 45, 90, 135 degrees. So there will be 26 features in total (f1 mean, f1 stdDev, f2 mean, f2 stdDev, ..., f13 mean, f13 stdDev). | |
