# template-matching
[](https://crates.io/crates/template-matching)
[](https://docs.rs/template-matching)

GPU-accelerated template matching library for Rust. The crate is designed as a faster alternative to [imageproc::template_matching](https://docs.rs/imageproc/latest/imageproc/template_matching/index.html).
## Installation
```bash
[dependencies]
template-matching = { version = "0.1.0", features = ["image"] }
```
## Usage
```rust
use template_matching::{find_extremes, match_template, MatchTemplateMethod, TemplateMatcher};
fn main() {
// Load images and convert them to f32 grayscale
let input_image = image::load_from_memory(include_bytes!("input.png")).unwrap().to_luma32f();
let template_image = image::load_from_memory(include_bytes!("template.png")).unwrap().to_luma32f();
let result = match_template(&input_image, &template_image, MatchTemplateMethod::SumOfSquaredDifferences);
// Or alternatively you can create the matcher first
let matcher = TemplateMatcher::new();
let result = matcher.match_template(&input_image, &template_image, MatchTemplateMethod::SumOfSquaredDifferences);
// Calculate min & max values
let extremes = find_extremes(&result);
}
```
