Firstly, thanks for a prompt reply.

what i actually meant was--- you are provided with an image. It is not known as to whether the image is an original camera output or it has been modified/tampered.

You are supposed to determine the authenticity of the image, and also , if the image is found to be a tampered one, we have to determine the region of the image where tampering has taken place.

Please reply even in case it is not clear. I shall explain it in more detail.
