Struct opencv::cudafeatures2d::CUDA_DescriptorMatcher

pub struct CUDA_DescriptorMatcher { /* private fields */ }

Abstract base class for matching keypoint descriptors.

It has two groups of match methods: for matching descriptors of an image with another image or with an image set.

Implementations

impl CUDA_DescriptorMatcher

pub fn create_bf_matcher(norm_type: i32) -> Result<Ptr<CUDA_DescriptorMatcher>>

Brute-force descriptor matcher.

For each descriptor in the first set, this matcher finds the closest descriptor in the second set by trying each one. This descriptor matcher supports masking permissible matches of descriptor sets.

Parameters

• normType: One of NORM_L1, NORM_L2, NORM_HAMMING. L1 and L2 norms are preferable choices for SIFT and SURF descriptors, NORM_HAMMING should be used with ORB, BRISK and BRIEF).

C++ default parameters

• norm_type: cv::NORM_L2

pub fn create_bf_matcher_def() -> Result<Ptr<CUDA_DescriptorMatcher>>

Brute-force descriptor matcher.

For each descriptor in the first set, this matcher finds the closest descriptor in the second set by trying each one. This descriptor matcher supports masking permissible matches of descriptor sets.

Parameters

• normType: One of NORM_L1, NORM_L2, NORM_HAMMING. L1 and L2 norms are preferable choices for SIFT and SURF descriptors, NORM_HAMMING should be used with ORB, BRISK and BRIEF).

Note

This alternative version of CUDA_DescriptorMatcher::create_bf_matcher function uses the following default values for its arguments:

• norm_type: cv::NORM_L2

fn empty(&self) -> Result<bool>

Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read
