Implementations

impl BRISK

pub fn create(

    octaves: i32,
    pattern_scale: f32
) -> Result<Ptr<BRISK>>

The BRISK constructor

Parameters

• thresh: AGAST detection threshold score.

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

C++ default parameters

• thresh: 30
• octaves: 3
• pattern_scale: 1.0f

pub fn create_with_pattern(

    index_change: &Vector<i32>
) -> Result<Ptr<BRISK>>

The BRISK constructor for a custom pattern

Parameters

• 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.

• d_max: 5.85f
• d_min: 8.2f
• index_change: std::vector()
