Skin / people detection in Java?

Question

Does anyone know about any Java library or framework that could allow me to detect people in a picture (jpg, png, etc..)?

I don't need to detect faces, nor recognize them.

All I need to know is if there is a human being present in a picture (or not).

What do you need this for? If you are look at a picture of the back of a person, should it work out this? — Peter Lawrey, Aug 07 '13 at 20:01
This is very vague. Do they have to have skin exposed? What if it is just part of a person (hand, leg, ect.)? What if it is a silhouette? What if it is an image of an image containing a person? These are all research questions that people work on for years, **not** something you ask on SO. — Austin Henley, Aug 07 '13 at 20:24
Questions asking us to recommend or find a tool, library or favorite off-site resource are off-topic for Stack Overflow as they tend to attract opinionated answers and spam. — Brian Roach, Aug 07 '13 at 20:25
That said, I also recommend OpenCV. If you are doing this for commercial purpose, consider FaceVACS (it is very expensive but very high quality). — Jason C, Aug 07 '13 at 20:26
The goal is to make sure a user does not upload a picture that depicts a person to my web application. I need to allow only pictures of houses (interior/exterior), desert landscapes (city, country side, and so on ..) — Gabriel C, Aug 07 '13 at 20:43

I used OpenCV for a project at university. It is open source and supports many different languages, also Java. Furthemore, it has a big user community.

Here's someone doing similar things with OpenCV http://stackoverflow.com/questions/12968576/opencv-skin-detection – Gubatron Aug 07 '13 at 20:19
Thank you very much. If I don't find any pure Java solution I will check this project. – Gabriel C Aug 07 '13 at 20:45

Have you checked Scholar.Google? This is a fairly common task in image processing research.

The methods that come to mind are:

Viola-Jones objects (based on Haar cascades and already implemented in OpenCV)
Edge detection
Neural networks
Human skin color (very naive)
Blob detection (Matlab is good language for this)

Thank you very much. But I really need this to be pure Java. If I don't find any open source solution I'll have to start a project from scratch and then I'll use all the available literature as a basis for my implementation. – Gabriel C Aug 07 '13 at 20:52
