Struct pico_detect::Detector

pub struct Detector { /* fields omitted */ }

Implements object detection using a cascade of decision tree classifiers.

Implementations

impl Detector

pub fn classify_region(
    &self,
    image: &GrayImage,
    roi: &Point3<u32>
) -> Option<f32>

Estimate detection score for the region of interest.

Arguments

• image - Target image.
• roi - region of interest:
  • roi.x position on image x-axis,
  • roi.y position on image y-axis,
  • roi.z region size.

pub fn run_cascade_mut(
    &self,
    image: &GrayImage,
    detections: &mut Vec<Detection>,
    params: &CascadeParameters
)

Run cascade and push detections to the existing collection.

pub fn run_cascade(
    &self,
    image: &GrayImage,
    params: &CascadeParameters
) -> Vec<Detection>

Run cascade with a new empty detection collection.

pub fn find_clusters(
    &self,
    image: &GrayImage,
    params: &CascadeParameters,
    threshold: f32
) -> Vec<Detection>

Run cascade and clusterize resulted detections using Self::cluster_detections

pub fn cluster_detections(
    detections: Vec<Detection>,
    threshold: f32
) -> Vec<Detection>

Clusterize detections by intersection over union (IoU) metric.

Arguments

• detections -- mutable collection of detections;
• threshold -- if IoU is bigger then a detection is a part of a cluster.

pub fn from_readable(readable: impl Read) -> Result<Self, Error>

Create a detector object from a readable source.
