    It's easy, just import facialrecognition.java

    Just kidding. Start by reading up on facial recognition. Then you'll know what you need and can start looking for existing packages or develop your own if you need something novel.

    I have learn t on images and computer graphics. I also have skills in java, If you have an Idea on image reconation, thats what im looking for.

    I would assume a facial recognition project consists of three parts:

    - First there's a biometrics part. You need to know what facial features characterize a face. A face biometric probably is a set of relative distances between facial components such as lips, eyes, nose, ears, chin, cheekbones etcetera. You could also include eye and skin color and special features such as scars and tattoos.

    - Secondly there's a feature extraction part. The features needed for the biometrics must be extracted from an image of the face (or from several images from different angles to get a 3D view).

    - Thirdly there's a database search part. The biometric of one face must be compared with the biometric of many faces to check whether there's a match. The matching must handle some degree of "fuzziness" since the biometric of the same face may vary slightly depending on recording circumstances. I know a mathematical technique called Wavelets have been successfully used to perform this kind of searches very quickly.

    I strongly recommend you start simple. For example a face could be reduced to a rectangle with two dots inside. The rectangles vary in shape and the dots vary in location. The face biometric could consist of just three measures: The distance between the dots, the ratio between the short and long rectangle sides, and the angle between a line through the dots and the short rectangle side. This involves basic feature extraction at the level of an introductory image recognition class at a college or university. You should find fully worked out examples in any suitable textbook.

    For more advanced feature extraction you really need to make a literature search. But as I suggested, don't get bogged down in that. Get a simplified but functionally complete well-designed program up and running as early as possible, then refine it in small steps.

    The document is language agnostic. It shows you what HTTP method to use (i.e. POST), the URL to post to, and what data to send depending on what functionality you need. The post requests returns a JSON you'll need to parse on your end.
