Crate img_hash

A crate that provides several perceptual hashing algorithms for images. Supports images opened with the image crate from Piston.

extern crate image;
extern crate img_hash;
 
use img_hash::{HasherConfig, HashAlg};

fn main() {
    let image1 = image::open("image1.png").unwrap();
    let image2 = image::open("image2.png").unwrap();
     
    let hasher = HasherConfig::new().to_hasher();

    let hash1 = hasher.hash_image(&image1);
    let hash2 = hasher.hash_image(&image2);
     
    println!("Image1 hash: {}", hash1.to_base64());
    println!("Image2 hash: {}", hash2.to_base64());
     
    println!("Hamming Distance: {}", hash1.dist(&hash2));
}

Re-exports

pub extern crate image;

Structs

Hasher	Generates hashes for images.
HasherConfig	Start here. Configuration builder for Hasher.
ImageHash	A struct representing an image processed by a perceptual hash. For efficiency, does not retain a copy of the image data after hashing.

Enums

FilterType	Available Sampling Filters
HashAlg	Hash algorithms implemented by this crate.

Traits

DiffImage	Image types that can be diffed.
HashBytes	Interface for types used for storing hash data.
Image	Shorthand trait bound for APIs in this crate.
