我在phpclasses.org上面偶然發現一個很有用的,由Bakr Alsharif開發的可以幫助開發者基于皮膚像素點來檢測圖片裸照的類文件.
它會分析在一張圖片的不同部分使用的顏色,并決定其是否匹配人類皮膚顏色的色調.
作為分析的結果,他會返回一個反映圖片包含裸露的可能性的分值.
此外,他還可以輸出被分析的圖片,上面對使用給定顏色的膚色的像素進行了標記.
當前它可以對PNG,GIF和JPEG圖片進行分析.
下面展示了如何使用這個PHP類.
讓我們先從包含裸體過濾器,nf.php文件開始.
- include ('nf.php');
接下來,創建一個新的名叫ImageFilter的類,然后把它放到一個叫做$filter的變量中.
- $filter = new ImageFilter;
獲取圖片的分值并將其放到一個$score變量中.
- $score = $filter -> GetScore($_FILES['img']['tmp_name']);
如果圖片分值大于或等于60%,那就展示一條(告警)消息.
- if($score >= 60){
- /*Message*/
- }
下面是所有的PHP代碼:
- <?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.";
- }
- }
- ?>
