The algorithm parameters:
|
static |
hessianThreshold | Threshold for hessian keypoint detector used in SURF. |
nOctaves | Number of pyramid octaves the keypoint detector will use. |
nOctaveLayers | Number of octave layers within each octave. |
extended | Extended descriptor flag (true - use extended 128-element descriptors; false - use 64-element descriptors). |
upright | Up-right or rotated features flag (true - do not compute orientation of features; false - compute orientation). |
