中值滤波
原图像画面清晰,添加了椒盐噪声以后图像上出现了明显噪声,经不同模板的中值滤波处理后图像上的噪声被虑去,但使得图像变得模糊,并且,使用的模板越大,去噪声效果越好,同时图像也越模糊。滤波效果明显优于平滑滤波。
(Median filtering the original image, a clear picture of the Salt and pepper noise added after the image there is a clear noise, and by different template after median filtering has been taking into account the noise on the image to go, but makes the image become blurred, and, using the template more large, to noise, the better the effect, while the more blurred the image. Filtering effect is superior to smoothing.)

adapQuad
迭代自适应Simpson,Lobatto积分
In almost every standard book on numerics quadrature algorithms like the adaptive Simpson or the adaptive Lobatto algorithm are presented in a recursive way. The benefit of the recursive programming is the compact and clear representation. However, recursive quadrature algorithms might be transformed into iterative quadrature algorithms without major modifications in the structure of the algorithm.
We present iterative adaptive quadrature algorithm (adaptiveSimpson and adaptiveLobatto), which preserves the compactness and the clarity of the recursive algorithms (e.g. quad, quadv, and quadl). Our iterative algorithm provides a parallel calculation of the integration function, which leads to tremendous gain in run-time, in general. Our results suggest a general iterative and not a recursive implementation of adaptive quadrature formulas, once the programming language permits parallel access to the integration function. For details the attached PDF file Conrad_08.pdf.

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)
