Struct SignalErosionParams 

pub struct SignalErosionParams {
    pub threshold: f64,
    pub depth_cap: usize,
    pub global_erosions: usize,
    pub bias_sigma: f64,
    pub min_component: usize,
}

Signal-gated erosion parameters. The default is the QSM-CI harmonization setting.

Fields

threshold: f64

Signal gate as a fraction of the in-mask median of the coil-debiased magnitude (default 0.80). Above ~0.85 it starts over-carving.

depth_cap: usize

Never remove a voxel more than this many voxels below the original mask surface (default 5). Bounds the erosion by construction: without it, the peel follows low-signal sulcal and interhemispheric CSF deep into healthy cortex. 0 disables the cap.

global_erosions: usize

Plain 6-connected erosions applied before the signal gate (default 1). Trims the bright one-voxel skull/CSF sliver a mask often carries, which no signal gate can catch.

bias_sigma: f64

Gaussian scale in voxels of the receive-coil bias estimate divided out of the magnitude (default 12).

min_component: usize

Keep every connected component with at least this many voxels, not just the largest (default 1000): a capped peel can sever small real pieces off thin structures.
