pub struct FeatureDetector { /* private fields */ }

Implementations§

Source§

impl FeatureDetector

Source

pub fn new(detector_type: FeatureType) -> Self

Source

pub fn with_max_features(self, max: usize) -> Self

Sets the maximum number of features to detect.

Source

pub fn detect<B: Backend>(&self, image: &Image<B>) -> Result<Vec<KeyPoint>>

Detects keypoints in an image using the FAST corner detector. FAST checks a circle of 16 pixels around each candidate point and requires at least 12 contiguous pixels to be brighter or darker.

Source

pub fn compute<B: Backend>( &self, image: &Image<B>, keypoints: &[KeyPoint], ) -> Result<Tensor<B, 2>>

Computes ORB descriptors for detected keypoints. ORB uses BRIEF descriptors with rotation invariance via intensity centroid. Returns a descriptor tensor of shape [NumKeyPoints, DescriptorDim].
