Struct Multiscaler

pub struct Multiscaler { /* private fields */ }

Multiscale object detection parameters.

Implementations

impl Multiscaler

pub fn new( min_size: u32, max_size: u32, shift_factor: f32, scale_factor: f32, ) -> Result<Self, MultiscalerError>

Create a new multiscale detector with specified parameters.

Arguments

• min_size – minimum size of the square region to detect;
• max_size – maximum size of the square region to detect;
• shift_factor – factor to shift the detection window;
• scale_factor – factor to scale the detection window.

pub fn min_size(&self) -> u32

Returns the minimum size of the square region to detect.

pub fn max_size(&self) -> u32

Returns the maximum size of the square region to detect.

pub fn shift_factor(&self) -> f32

Returns the factor to shift the detection window.

pub fn scale_factor(&self) -> f32

Returns the factor to scale the detection window.

pub fn run<F>(&self, rect: Rect, f: F)

where F: FnMut(Square),

Run multiscale detection on the specified rectangle.

Arguments

• rect – rectangle to run detection on;
• f – function to call for each generated square region.

pub fn count(&self, rect: Rect) -> usize

Count the number of square regions that would be generated by running multiscale detection on the specified rectangle.

pub fn collect(&self, rect: Rect) -> Vec<Square>

Collect all square regions generated by running multiscale detection on the specified rectangle.

Trait Implementations

impl Clone for Multiscaler

fn clone(&self) -> Multiscaler

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Multiscaler

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Multiscaler

fn eq(&self, other: &Multiscaler) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
