Enum FrameSchedule 

pub enum FrameSchedule {
    Sequential,
    BrightfieldFirst,
    SpiralOut,
    RandomShuffle {
        seed: u64,
    },
    SnrWeighted,
}

Rule for ordering acquisition frames within each reconstruction iteration.

Variants

Sequential

Ascending acquisition-frame index.

BrightfieldFirst

Increasing transverse illumination magnitude, approximating brightfield first.

SpiralOut

Increasing polar radius then azimuth in transverse-wave-vector space.

RandomShuffle

Deterministic per-iteration pseudorandom permutation.

Fields

seed: u64

Base random seed combined with the zero-based iteration number.

SnrWeighted

Highest empirical shot-noise SNR first. This requires measurements and is applied by Self::order_for_problem; Self::order retains sequential order because a compiled model alone contains no signal data.

Implementations

impl FrameSchedule

pub fn order(&self, model: &ImagePlaneModel, iteration: usize) -> Vec<usize>

Returns a model-only frame order.

Self::SnrWeighted cannot be estimated from model geometry, so this method returns sequential order for that variant. Reconstruction runners use Self::order_for_problem and therefore have access to measurements.

pub fn order_for_problem<M: MeasurementRead>( &self, problem: &ReconstructionProblem<M>, iteration: usize, ) -> Result<Vec<usize>>

Returns a frame order using both the model and measured intensities.

The SNR-weighted schedule ranks frames by frame_weight * sqrt(mean(max(measured - known_background, 0))) over unmasked pixels. This is an empirical Poisson shot-noise proxy, not a camera-noise calibration. Zero-weight or fully masked frames are placed last, and equal scores retain ascending frame-index order.
