Struct TemplateStats 

pub struct TemplateStats { /* private fields */ }

A template prepared for repeated scoring: its masked pixels, their values, and the moments correlation needs.

Preparing it is where a crop with nothing to match — no visible pixels, or one flat colour — is refused. A caller that polls therefore cannot discover that on poll sixty: it finds out before the loop, with the reason.

Implementations

impl TemplateStats

pub fn prepare(tpl: &Template) -> Result<Self, LocateError>

Prepare tpl for scoring, refusing a crop that cannot match.

pub const fn span(&self) -> Size

The masked extent — how much room a placement needs.

pub fn score_at( &self, screen: &GrayImage, at: Point, ) -> Result<f64, LocateError>

Normalized cross-correlation with the template placed at at.

Fixed-location scoring: no search and no ambiguity, which is locate’s job. This is what wait polls with — a region that has not moved is answered by reading its own pixels, rather than re-scanning a whole frame to rediscover where it already is.
