Python: |

| retval | = | cv.AffineFeature_create( | backend[, maxTilt[, minTilt[, tiltStep[, rotateStepBase]]]] | ) |
- Parameters
-
backend | The detector/extractor you want to use as backend. |
maxTilt | The highest power index of tilt factor. 5 is used in the paper as tilt sampling range n. |
minTilt | The lowest power index of tilt factor. 0 is used in the paper. |
tiltStep | Tilt sampling step \(\delta_t\) in Algorithm 1 in the paper. |
rotateStepBase | Rotation sampling step factor b in Algorithm 1 in the paper. |

Python: |
---|
| retval | = | cv.AffineFeature.getDefaultName( | | ) |
Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.
Reimplemented from cv::Feature2D.
