how to detect face occluded image??
I want to detect helmet, mask if the person wears in security places like ATM etc. Can anyone help me for this problem.

I wouldn't try to detect the different features of all types of hoods. What I would do is following these steps:
Since Viola and Jones is quite influenced by masking and stuff, it will fail quickly if no actual face features are present.
I think the problem you give here is very broad and you need to start by narrowing it to some small problems. For example, are you talking about images or live video?
To find some known object in image you can try to implement some kind of features matching algorithm. The main idea is: - Extract useful features from images of people with helmet/mask - Learn what are the main features unique to person with helmet/mask - Find the same features in new image
Have a look at the feature2d
and objdetect
modules tutorials, there is a lot of information about features there.
The downside to feature matching is that the range of possibilities is endless and thus it will take way to long to process a single image. I wouldn't suggest such an approach.
