Struct SimulatorConfig 

pub struct SimulatorConfig {
    pub pos_thres: f32,
    pub neg_thres: f32,
    pub sigma_thres: f32,
    pub refractory_us: i64,
    pub cutoff_hz: f32,
    pub leak_rate_hz: f32,
    pub shot_noise_rate_hz: f32,
    pub seed: u64,
    pub upsample: Upsample,
    pub max_upsample: usize,
}

Pixel-model parameters. Defaults follow v2e’s for a typical DVS.

Fields

pos_thres: f32

Log-intensity increase that emits an ON event.

neg_thres: f32

Log-intensity decrease that emits an OFF event.

sigma_thres: f32

Standard deviation of the per-pixel Gaussian threshold mismatch, in log units.

refractory_us: i64

Minimum time between two events from the same pixel, in µs.

cutoff_hz: f32

Photoreceptor bandwidth for a white pixel, in Hz. 0 disables the lowpass.

leak_rate_hz: f32

Spontaneous ON events per pixel per second. 0 disables leak.

shot_noise_rate_hz: f32

Shot-noise events per pixel per second in the darkest pixels. 0 disables noise.

seed: u64

Seed for mismatch and noise, so a run is reproducible from its configuration.

upsample: Upsample

Frame subdivision — see Upsample.

max_upsample: usize

Ceiling on the sub-steps any one frame pair may be split into.

Adaptive upsampling is driven by the busiest pixel, so one high-contrast edge can push a whole 1080p frame to the ceiling — 64 full-sensor passes for that pair. Lowering this bounds the worst case at some cost in timestamp accuracy where the scene really is that fast; raising it buys accuracy on hard cuts. Clamped to 1..=4096.

Implementations

impl SimulatorConfig

pub fn ideal() -> Self

A noiseless, ideal sensor: fixed thresholds, no mismatch, bandwidth, leak or shot noise.

Not realistic, and not the default for that reason — but it is what makes the simulator testable, since an ideal pixel’s event count is an analytic function of the contrast.
