Definition

rust pub fn similarity_sad(before: &DynamicImage, after: &DynamicImage) -> Result<i32>

rust pub fn similarity_mad(before: &DynamicImage, after: &DynamicImage) -> Result<f32>

Usage

toml [dependencies] image = "0.23.4"

rust let image_a = image::open("before.png").unwrap(); let image_b = image::open("after.png").unwrap(); let difference = similarity_sad(&image_a, &image_b);
