What shall I do for my final year project (Digital watermarking)?

Hi,
I am doing my final year project on digital watermarking using MATLAB . I have been given the choice of what to investigate in digital watermarking. However I am finding it difficult to pick out a particular area in which to investigate. Can someone please suggest ideas?

I'm not in the field of watermarking/steganography so I can't make recommendations on what subfields of watermarking might be interesting for you to investigate. But, I'd start off with a description of why people might want to watermark, like branding, detect if their images or videos were "stolen", hidden transmission of messages, etc. Then I'd go into a survey of the different subfields, like visible watermarks, invisible watermarks, video bugs, steganography, etc. Then describe some methods, like replacement, averaging, LSB, Fibonnacci, etc. Describe ways of getting around watermarks, like scaling, rotation, adding noise, cropping, etc. Then describe how some methods are robust to these kinds of attacks, that is, the watermark can still be retrieved despite attempts to alter the image. Then if you're required to invent something new (unlikely for undergraduate students but required for graduate students), pick a method that you think you can improve on and try to code something up.

Hi
I decided to watermark digital image with DWT and DCT methods . I have tried to code for months now but just don't seem to get the grasp or how to start watermarking.
I was wondering if you could help me with this please?
