Class implementing the BRISK keypoint detector and descriptor extractor, described in LCS11 .

Required Methods

fn as_raw_mut_BRISK(&mut self) -> *mut c_void

Provided Methods

fn set_threshold(&mut self, threshold: i32) -> Result<()>

Set detection threshold.

Parameters

• threshold: AGAST detection threshold score.

fn set_octaves(&mut self, octaves: i32) -> Result<()>

Set detection octaves.

Parameters

• octaves: detection octaves. Use 0 to do single scale.

fn set_pattern_scale(&mut self, pattern_scale: f32) -> Result<()>

Set detection patternScale.

Parameters

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

Implementations

impl dyn BRISK + '_

pub fn create( thresh: i32, octaves: i32, pattern_scale: f32 ) -> Result<Ptr<dyn BRISK>>

The BRISK constructor

Parameters

• 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.

C++ default parameters

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

pub fn create_with_pattern( radius_list: &Vector<f32>, number_list: &Vector<i32>, d_max: f32, d_min: f32, index_change: &Vector<i32> ) -> Result<Ptr<dyn 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.

C++ default parameters

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

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

Parameters
