Image treatment method to prevent copying

摘要

The method involves detecting a zone corresponding to an object in a scene, and selecting pixels included in the zone of a sequence of a source image. The source image is processed so as to change color of the selected pixels or spectral composition of light emitted by the selected pixels such that the perceived color of the selected pixels is unchanged in the processed source image with respect to original source image. An independent claim is also included for a method for displaying a sequence of source images.
