我在PHPclasses.org上面偶然发现一个很有用的,由Bakr Alsharif开发的可以帮助开发者基于皮肤像素点来检测图片裸照的类文件.
它会分析在一张图片的不同部分使用的颜色,并决定其是否匹配人类皮肤颜色的色调.
作为分析的结果,他会返回一个反映图片包含裸露的可能性的分值.
此外,他还可以输出被分析的图片,上面对使用给定颜色的肤色的像素进行了标记.
当前它可以对PNG,GIF和JPEG图片进行分析.
下面展示了如何使用这个PHP类. 让我们先从包含裸体过滤器,nf.PHP文件开始.
接下来,创建一个新的名叫ImageFilter的类,然后把它放到一个叫做$filter的变量中.
如果图片分值大于或等于60%,那就展示一条(告警)消息.
<?php
/Include the Nudity Filter file/
include ('nf.php');
/Create a new class called $filter/
$filter = new ImageFilter;
/Get the score of the image/
$score = $filter -> Getscore($_FILES['img']['tmp_name']);
/If the $score variable is set/
if (isset($score)) {
/If the image contains nudity,display image score and message. score value if more than 60%,it is considered an adult image./
if ($score >= 60) {
echo "Image scored " . $score . "%,It seems that you have uploaded a nude picture.";
/If the image doesn't contain nudity/
} else if ($score < 0) {
echo "Congratulations,you have uploaded an non-nude image.";
}
}
?>
