{
    "require": {
        "inceddy/image-compare": "dev-master"
    }
}

概念

此比较背后的想法很简单。

  1. 去除背景变为白色
  2. 隔离剩余区域
  3. 比较两幅图中所有区域平均颜色和区域数量

示例

// Load first image
$image1 = Image::fromFile('demo_inputs/image1.png');

// Load second image to compare
$image2 = Image::fromFile('demo_inputs/image2.png');

// If both images have an known background substract it
$mask = Image::fromFile('demo_inputs/mask.png');
$image1 = $image1->subtract($mask, 15); // use 15% tolerance
$image2 = $image2->subtract($mask, 15); // use 15% tolerance

// Compare both images
$equal = $image1->compare($image2); // Returns a boolean value whether these images are equal or not

// Or if you are interessted in how equal they are
$diff = $image1->difference($image2); // Retuns a float between 1 and 0, where 1 is equal and 0 is total difference
