PHP でインテリジェントな画像処理と顔検出を実行するにはどうすればよいですか?

$source_image = imagecreatefromjpeg("test.jpg");
$destination_image = imagecreatetruecolor($new_width, $new_height);
imagecopyresampled($destination_image, $source_image, 0, 0, 0, 0, $new_width, $new_height, $original_width, $original_height);
imagejpeg($destination_image, null, $quality);

$source_image = imagecreatefromjpeg("test.jpg");
$destination_image = imagerotate($source_image, $angle, 0);
imagejpeg($destination_image, null, $quality);
