Digital video sequence tattooing process, involves selecting optimal tattooed displacement vector, based on preset criteria, such that modified coordinates of displacement vector are coordinates of optimal vector

摘要

The process involves inserting a tattooing bit on a displacement vector to obtain tattooed displacement vectors. Coordinates of the displacement vector are modified to be situated in a binary value zone of the bit. An optimal tattooed displacement vector is selected, based on preset criteria, in a manner such that the modified coordinates are the coordinates of the optimal vector. Independent claims are also included for the following: (a) a process for extracting tattooing of a video image sequence (b) a device for tattooing a video image sequence (c) a signal representing a video image sequence recorded on a support utilized in a computer (d) a computer program product having instruction to execute a process of tattooing a video image sequence.
