Jsteg
基于DCT的jsteg图像隐写及分析算法,MATLAB实现。
JSteg的算法主要思想是将秘密消息嵌入在量化后的DCT系数的最低比特位上,但对原始值为O、1的DCT系数不进行嵌入。提取秘密消息时,只需将载密图像中不等于0、l的量化DcT系数的LSB取出即可。(The main idea of the JSteg algorithm is to embed secret messages in the lowest bit of the quantized DCT coefficients, but the DCT coefficients of the original values are O and 1 are not embedded. When extracting secret messages, only the LSB of the quantized DCT coefficients not equal to 0 and l in the encrypted image can be taken out.)

Retinex-of-image-enhancement
本文提出了基于Retinex可变框架模型的图像增强算法。实验证明该算法不但能有效的增强图像的质量,还能避免Retinex算法中带来的光晕效应,同时算法速度与同类型的图像增强算法比较更快速。之后,将这种理论运用到对彩色图像增强中,取得了很好的处理效果。
(使用同方知网浏览器打开)(This paper presents a framework model based on variable Retinex image enhancement algorithm. Experiments show that this algorithm not only can effectively enhance the image quality, but also to avoid the Retinex algorithm brought halo effect, and algorithm speed and the same type of image enhancement algorithm is relatively faster. After this kind of theory to the enhancement of color images, achieved good treatment effect. (Text browser to use the same side open))
