-> VGG
Parameters
- desc (Optional)
- Type: Emgu.CV.XFeatures2DVGGDescriptorType
Type of descriptor to use - isigma (Optional)
- Type: SystemSingle
gaussian kernel value for image blur - imgNormalize (Optional)
- Type: SystemBoolean
use image sample intensity normalization - useScaleOrientation (Optional)
- Type: SystemBoolean
sample patterns using keypoints orientation - scaleFactor (Optional)
- Type: SystemSingle
adjust the sampling window of detected keypoints to 64.0f (VGG sampling window) 6.25f is default and fits for KAZE, SURF detected keypoints window ratio 6.75f should be the scale for SIFT detected keypoints window ratio 5.00f should be the scale for AKAZE, MSD, AGAST, FAST, BRISK keypoints window ratio 0.75f should be the scale for ORB keypoints ratio - dscNormalize (Optional)
- Type: SystemBoolean
clamp descriptors to 255 and convert to uchar CV_8UC1
