摘要: A system and method for infrared watermarking using gray component replacement other color removal schemes is shown. This includes providing a substrate implementing two absorption strategies, one with low the high absorption. These strategies are then combined in order to form gamuts substantially similar shapes. combination can be made by blending at areas where of do not meet or intersection gamuts. watermark printed along an image. The resultant image void artifacts while still having consistent signal.
