//! An implementation of the Canny edge detection algorithm in Rust. The base for
//! many computer vision applications.
//!
//! # Finding the edges in an image
//!
//! ```
//! extern crate edge_detection;
//! extern crate image;
//!
//! let source_image = image::open("testdata/line-simple.png")
//!     .expect("failed to read image")

//! let detection = edge_detection::canny(
//!     source_image,
//!     1.2,  // sigma
//!     0.2,  // strong threshold
//!     0.01, // weak threshold
//! );
//! ```

//! See the `canny` function for details on what each parameter means.
