I'm developing a social website that enables user to upload photos. What I want is when the user upload the photo, the system detects faces. And another is when it detects the face, it would suggest to crop the image, another thing that I do not know. When all is done, i want to save it in a specific folder. I would appreciate all helps. Thank you in advance.
How to auto detect face in uploaded using php?
Understanding the concept of face detection would be the very basic. Face detection is a computer technology that determines the locations and sizes of human faces in arbitrary (digital) image. It detects facial features and ignores anything else, such as trees, building and etc.
There are many algorithms implementing this as binary pattern-classification. It is a task of classifying members of a given set of objects into two groups on the basis of whether they have some property or not. There was a library called OpenCV (Open Source Computer Vision) that can make this face detection easier. You can also download PHP Face detect. Hope this can help you. Good luck.
