LBP
线性反投影算法(Linear Back Projection,简称 LBP)又称累加法,是最早使用的一种简单(ECT图像重建)成像算法。它将通过某点的所有投影射线进行累加,再反向估算出该点的密度值。从成像观点分析,它是不完全的雷登逆变换(完整的雷登逆变换包括微分、希尔伯特变换、反投影和归一化等步骤)。(Linear back projection algorithm (Linear Back Projection, referred LBP), also known as cumulative method, is the first to use a simple (ECT image reconstruction) imaging algorithms. It accumulates all projection rays through a point, then reverse the estimated density value of the point. From the image point of view analysis, it is not exactly the inverse transform Leiden (Leyden complete inverse transformation involving differential Hilbert transform backprojection and normalization steps, etc.).)

JSteg
JSteg隐写技术matlab实现代码--基本思想:用秘密信息比特直接替换JPEG图像中量化后DCT系数的最低比特位,但若量化后DCT系数为0或者1,则不进行处理。(DCT系数的LSB嵌入)
(JSteg steganography matlab code- the basic idea: direct replacement with the secret information bits JPEG image quantized DCT coefficients in the least significant bit, but if the quantized DCT coefficient is 0 or 1, no processing. (DCT coefficients LSB embedding))
