为避免多幅图像之间的加性串扰，在隐藏和提取过程中，通过计算机生成的双纯相位掩模将它们在菲涅耳域中独立定位，从而使它们彼此分离，甚至与宿主图像分离。灰度图像以及白底和黑底的二值图像可同时隐藏在该系统中。还使用级联迭代算法研究了该系统对于这三种多幅图像的隐藏容量。同时也分析了该系统的安全性和复用参数。
To avoid additive cross-talk among multiple images, they are separated from each other and even from the host image in the hiding and the extraction process by locating them independently in the Fresnel domain with computer-generated double phase-only masks. Gray images and white-ground and black-ground binary images can be hidden in the system at the same time. The hiding capacity of the system as to these three types of multiple image has also been investigated using a cascaded iterative algorithm. The security and the multiplexing parameters of the system are analyzed as well.
