Struct ComponentLabels 

pub struct ComponentLabels {
    pub labels: Vec<u32>,
    pub num_components: usize,
    pub height: usize,
    pub width: usize,
    /* private fields */
}

Result of connected_components.

Fields

labels: Vec<u32>

Row-major [height × width] label image; 0 is background and 1..=num_components identifies each connected region.

num_components: usize

Number of distinct foreground components.

height: usize

Image height.

width: usize

Image width.

Implementations

impl ComponentLabels

pub fn sizes(&self) -> &[usize]

Per-component pixel counts, indexed by label - 1.

pub fn size_of(&self, label: u32) -> usize

Pixel count of a specific label (0 for background or an out-of-range label).

pub fn bounding_boxes(&self) -> Vec<[usize; 4]>

Axis-aligned bounding boxes of every component as inclusive [x_min, y_min, x_max, y_max], indexed by label - 1.

Trait Implementations

impl Clone for ComponentLabels

fn clone(&self) -> ComponentLabels

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentLabels

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

Formats the value using the given formatter.
