Struct CheckerboardComplex 

pub struct CheckerboardComplex {
    pub dims: [usize; 2],
    pub data: Vec<bool>,
}

Cubical complex for image topology (checkerboard-like).

Represents a binary image as a cubical complex and computes its topological features.

Fields

dims: [usize; 2]

Grid dimensions [nx, ny]

data: Vec<bool>

Binary image data (true = filled voxel)

Implementations

impl CheckerboardComplex

pub fn new(dims: [usize; 2], data: Vec<bool>) -> Self

Creates a cubical complex from a binary grid.

Arguments

• dims - Grid dimensions [nx, ny]
• data - Binary values row-major

pub fn filled_disk(size: usize, radius: f64) -> Self

Creates a filled disk of given radius in a grid.

pub fn annulus(size: usize, r_inner: f64, r_outer: f64) -> Self

Creates an annulus (ring) in a grid.

pub fn volume(&self) -> usize

Counts the number of filled voxels.

pub fn euler_characteristic_2d(&self) -> i64

Computes the Euler characteristic via the cubical formula.

χ = V - E + F for 2D cubical complex
