Jsteg
Jsteg算法实现,Jsteg是一种基于JPEG的常用信息隐藏算法步骤如下:
首先,把掩体图像分为不重叠的8*8的子块,对每一子块进行DCT并对变换得到的DCT系数进行量化 其次,将待隐藏的信息进行加密,将加密结果嵌入到量化后值不为0,1或-1的DCT系数的最
低有效位(LSB)中,其嵌入顺序是按zigzag扫描顺序进行的。最后,用JPEG的嫡编码(包括哈夫曼编码,游程编码及DPCM)对嵌入秘密信息后的每一子块进行编码,从而得到一个含有秘密信息的JPEG stego文件。(Jsteg Algorithm)

超分辨率复原(分块处理)
将样本库中的高分辨率图象和低分辨率图象分别做分块处理,当新输入一幅低分辨率图象时,分成小块到样本库中寻找最匹配的高分辨率块,然后复原出高分辨率图象。(Superresolution recovery (block processing) for a sample of high-resolution images and low-resolution images respectively block , when the new importation of a low-resolution image, divided into small samples to find the most matching high-resolution block, then recovery from high-resolution images.)
