Struct DefaultEpochPolicy 

pub struct DefaultEpochPolicy {
    pub segment_angle_threshold: f32,
    pub segment_zoom_threshold: f32,
    pub segment_displacement_threshold: f32,
    pub compensate_min_confidence: f32,
    pub degrade_on_small_motion: bool,
    pub ptz_deadband: f32,
}

Default epoch policy based on configurable thresholds.

Covers the common case: large PTZ jumps → segment, small motions → degrade, high-confidence transforms → compensate.

Fields

segment_angle_threshold: f32

Pan/tilt delta (degrees) above which a PTZ move triggers Segment. Below this, triggers Degrade. Default: 15.0.

segment_zoom_threshold: f32

Zoom ratio change above which a zoom move triggers Segment. Default: 0.3.

segment_displacement_threshold: f32

Inferred-motion displacement (normalized coords) above which triggers Segment. Default: 0.25.

compensate_min_confidence: f32

Minimum confidence for a Compensate decision (instead of Segment) when a transform is available. Default: 0.8.

degrade_on_small_motion: bool

If true, small motions below segment thresholds produce Degrade instead of Continue. Default: true.

ptz_deadband: f32

Minimum PTZ telemetry delta (degrees for pan/tilt, ratio for zoom) below which changes are treated as sensor noise and ignored. Prevents floating-point jitter from triggering spurious Degrade events when the camera is at rest. Default: 0.01.
