hi guys.

I am working on a project which requires me to determine whether a given image is an original camera ouput or it is morphed in any which way.

I am supposed to use Matlab for the project(Image Processing Toolbox).

I have done extensive research on the internet.

The problem i am facing is that, all the articles i find require me to make use of the original image. But then, having the original iamge is a very rare case.

Can somebody with any relevant info guide me a little .

Any help will be highly appreciated.

Specifically, if anybody knows links which help in image authentication WITHOUT USING ORIGINAL IMAGE, please reply.

Thanks again.
