Enum MotionEstimation 

#[non_exhaustive]
pub enum MotionEstimation {
    Auto,
    Direct,
    Chained {
        refine_radius: u32,
    },
}

How motion toward a temporal neighbour is estimated.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Auto

Picks Direct or Chained from the temporal radius when the denoiser is built.

MotionEstimation::resolve describes the rule and where it came from.

Direct

Matches every neighbour against the centre frame directly, at the configured search radius.

The cost grows with the temporal radius, because each neighbour repeats the whole coarse and fine search.

Chained

Measures motion only between adjacent frames, once per pushed frame.

Those per-step vectors are then joined into a seed for each neighbour, and a small seeded search cleans up whatever drift is left.

Fields

refine_radius: u32

The search radius for the seeded refinement pass, in pixels at the finest pyramid level.

It can be small, because the joined seed already carries most of the real movement.

Implementations

impl MotionEstimation

pub fn chained_default() -> MotionEstimation

Builds a Chained estimation with the library’s default refinement radius.

pub fn resolve(self, temporal_radius: u32) -> MotionEstimation

Resolves Auto against the temporal radius, always returning a concrete Direct or Chained.

Direct and Chained pass through unchanged whatever the radius. [CHAINED_RADIUS_THRESHOLD] is where the switch happens.
