Furthermore this algorithm has no influence on such applications as edge detection and image classification of the disguised remote sensing image which has hidden the secrete information.
此外，该算法对隐藏了机密信息后的伪遥感影像的各种应用，如边缘检测和影像分类等均没有影响。
The image of point target in the imaging area is only several or dozens of pixels. And its strength is relatively weak and drowned in the noise, no obvious size, shape, texture, and other information.
点目标的成像面积仅为几个或几十个象素，目标强度相对较弱，无明显的尺寸、形状、纹理信息可供后续处理系统进行分析使用。
When single CGH is reconstructed, no information will be observed, while two alignment combined phase-only CGHs are reconstructed, the recorded information will be read out on the image plane.
单独再现每一张全息图时无法观察到原物体信息，而将两全息图对准合在一起时，则可在计算全息图的观察面上得到原来的物体信息。
