论文摘要
在本文中，我们提出了一种新型的基于内容的图像回归方案，该方案使我们能够使用普通图像和可压缩的加密图像的混合物，称为“加密 - 然后压缩（ETC）图像”。在拟议的方案中，从ETC图像和普通图像中提取了扩展的简单描述符，因此可以使用普通图像和加密图像的混合使用。在一个实验中，即使具有普通图像和加密图像的混合物，提出的方案被证明具有与普通图像相同的检索性能。
In this paper, we propose a novel content-based image-retrieval scheme that allows us to use a mixture of plain images and compressible encrypted ones called "encryption-then-compression (EtC) images." In the proposed scheme, extended SIMPLE descriptors are extracted from EtC images as well as from plain ones, so the mixed use of plain and encrypted images is available for image retrieval. In an experiment, the proposed scheme was demonstrated to have almost the same retrieval performance as that for plain images, even with a mixture of plain and encrypted images.
