[WM]: direction tp pursue research in video watermarking

[vhj@comp.coep.org.in]

  Hello friends
I would like to pursue my P.hd   research work in video watermarking. I
got hundreds of paper from IEEE   and ACM related to video watermarking. I
read few of them.
Different approaches used for Video watermarking are embedding WM in raw/ Compressed video, in low frequency coefficients/high
frequency coefficients in DCT block, in motion vector, using temporal wavelet transform , discrete wavelet transform, hybrid
approach, spread spectrum approach, in VLC domain, in the 3D DWT domain and many more, Is there any further scope for research work
in this area? As I got plenty of papers  is there saturation in  this area.? But in many recent papers I read that it is still
active field of research.  I am confused. Can any body guide me in this context, in which direction should I move?

Vandana
