From still picture to real-time video watermarking

In the past few years,much research on watermarking has focused on improving robustness to attacks on still pictures.The starting point of the present study was an R & D algorithm for still images, which, though not optimized, offered a good trade-off in terms of capacity, visibility and robustness, and working in a full blind manner.We focused on adapting it to video and on optimising it for the world of embedded terminals such as digital still cameras, digital television, wireless terminals, where the computing power and storage resources of a PC are not available. This work is the result of a close collaboration between the Eurecom research institute and STMicroelectronics
