Struct TrackParams 

pub struct TrackParams {
    pub window_size: usize,
    pub max_iterations: usize,
    pub min_eigen_threshold: f32,
}

Lucas-Kanade parameters of a tracking call.

The fields are named so that they cannot be swapped unnoticed. For 8-bit images, for example:

use optical_flow_lk::{DEFAULT_MIN_EIGEN_THRESHOLD, TrackParams};

let params = TrackParams {
    window_size: 21,
    max_iterations: 30,
    min_eigen_threshold: DEFAULT_MIN_EIGEN_THRESHOLD,
};

Fields

window_size: usize

Side of the square search window in pixels; must be odd.

max_iterations: usize

Most iterations per pyramid level, see CONVERGENCE_EPSILON.

min_eigen_threshold: f32

Windows whose minimum gradient eigenvalue, normalized by the window area, is below this value are reported as TrackStatus::LowTexture. In (grey levels / pixel)^2 for 8-bit images, see DEFAULT_MIN_EIGEN_THRESHOLD; in (input unit / pixel)^2 for the f32 tracker, which has no default.
