Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

The BRISK constructor for a custom pattern, detection threshold and octaves

thresh

AGAST detection threshold score.

octaves

detection octaves. Use 0 to do single scale.

patternScale

apply this scale to the pattern used for sampling the neighbourhood of a keypoint.

_3

3 argument (IntVector).

radiusList

defines the radii (in pixels) where the samples around a keypoint are taken (for keypoint scale 1).

numberList

defines the number of sampling points on the sampling circle. Must be the same size as radiusList..

dMax

threshold for the short pairings used for descriptor formation (in pixels for keypoint scale 1).

dMin

threshold for the long pairings used for orientation determination (in pixels for keypoint scale 1).

indexChange

index remapping of the bits.

_5

5 argument (number).

Returns

The xfeatures2d_BRISK | null result.
