System and method for analyzing and marking film
摘要:
A system and method for analyzing and marking a film image for providing a marked film with robust marks which have a high survival rate during, e.g., unauthorized duplication. The present invention provides the ability to facilitate the choosing of ideal locations of marks for marking a film image by recommending potential marking locations based on the survivability of the mark against different background colors. The system and method provides for selecting at least two potential marking areas in at least one frame of the film, saturating the at least two potential marking areas in a predetermined color of a mark, calculating a root mean square error (RMSE) of each of the at least two potential marking areas and an area surrounding each potential marking area, and determining which of the at least two potential marking areas has the lowest RMSE, i.e., the recommend marking location.
