A library for detecting edges in images.

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")
    .to_luma();
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.
