This class can compare two images to find if they are similar.

It resizes the images to a 8x8 square, converts the result into grey scale images, takes the color mean, and computes the hammering distance of the images' bits.

The class returns a number that is below 10 if the images are similar.

Search uploaded images for similar images

Example

<?php
require 'image.compare.class.php';
 
/*
    these two images are almost the same so the hammered distance will be less than 10
    try it with images like this:
        1. two complatly different image
        2. the same image (returned number should be 0)
        3. the same image but with different size, even different aspect ratio (returned number should be 0)
        4. the same image with slightly different colors / lights etc. (returned number should be under 10)
    you will see how the returned number will represent the similarity of the images.

$class = new compareImages;
echo $class->compare('1.jpg','2.jpg');
