Struct DigitalImageCorrelation 

pub struct DigitalImageCorrelation {
    pub points: Vec<DicPoint>,
    pub min_correlation: f64,
}

Digital Image Correlation displacement field reader and processor.

Fields

points: Vec<DicPoint>

DIC data points.

min_correlation: f64

Minimum accepted correlation coefficient.

Implementations

impl DigitalImageCorrelation

pub fn new(min_correlation: f64) -> Self

Create an empty DIC reader with a given minimum correlation threshold.

pub fn from_csv(csv: &str, min_correlation: f64) -> Result<Self, String>

Parse from CSV: x,y,u,v,correlation rows.

pub fn filter_by_correlation(&mut self)

Filter out points below the minimum correlation threshold.

pub fn compute_strain_field( &self, grid_spacing: f64, ) -> Vec<(f64, f64, StrainTensor2D)>

Compute strain field using finite differences on a regular grid.

Returns a vector of (x, y, StrainTensor2D) for interior points.

pub fn mean_displacement(&self) -> f64

Average displacement magnitude across all (valid) points.

pub fn max_displacement(&self) -> f64

Maximum displacement magnitude.
