Face detection in pure PHP (without OpenCV) / Blog de Maurice Svay

Une résumé en français est disponible en fin d’article. Lately, I’ve been looking for ways to detect faces in photos with PHP. Nowadays, face detection is built in many consumer products (camera obviously, but also Google and iPhoto), and seems to be a pretty common job. So I expected to find many solutions for doing it with PHP. Learning about face detection So I started to think about implementing it myself. Always look at what others are doing Then I looked for existing implementations in other languages. The code Update: the code has moved to Once the code converted to PHP, here’s the result: And you simply use the class this way: $detector = new Face_Detector('detection.dat'); $detector->face_detect('maurice_svay_150.jpg'); $detector->toJpeg(); Which gives the following result: The code requires GD and is a bit slow but should work on most PHP servers.
