Parameters
- pt
- Type: OpenCvSharpPoint2f
Coordinate of the point - size
- Type: SystemSingle
Feature size - angle (Optional)
- Type: SystemSingle
Feature orientation in degrees (has negative value if the orientation is not defined/not computed) - response (Optional)
- Type: SystemSingle
Feature strength (can be used to select only the most prominent key points) - octave (Optional)
- Type: SystemInt32
Scale-space octave in which the feature has been found; may correlate with the size - classId (Optional)
