| Research Abstract |
In this research, we investigated the methods of information hiding for H. 264/AVC. We proposed two methods based on the intra prediction and a method based on the inter prediction. We evaluated these methods by computer simulation using six sequences and showed the relationship of embedded bits, image degradation and computational cost to bit rates. By combining intra and inter predictions, it can embed more information bits.
