Function diffimg::diff

pub fn diff(image_a: &[u8], image_b: &[u8], precision: f64) -> f64

Compute the amount of difference between two images using their raw bytes.

Receives two &[u8] (the raw bytes of the images to be compared) and returns a f64 between 0 and 1, representing how much both images differ from each other, where 0 means they are completely equal and 1 means they are completely different. Presicion value goes from 0 to 1 and determines the number of chunks that is going to be used.

Example

use image::*; // To get raw-pixels
use diffimg;

let image1 = image::open("tests/images/image1.png").expect("Failed to open image");
let image2 = image::open("tests/images/image2.png").expect("Failed to open image");
     
let diff = diffimg::diff(&image1.to_bytes(), &image2.to_bytes());
