LSB
利用LSB算法去实现了电子水印技术。代码完全实现了嵌入以及提取, 算法同时包含了4种攻击算法以及利用psnr测量提取的水印和攻击后提取的水印(This algorithm describes digital watermark technique by using LSB. This code implement embedding and extraction. At the meanwhile, this algorithm includes 4 different kinds of attacks and in the end, measure psnr between extracted watermark and attacked extracted watermark)

参数假设检验:对差异进行定量的分析,确定其性质,是随机误差还是系统误差.为给出两者界限,找一检验统计量T,在H0成立下其分布已知。(Parameter hypothesis test: a quantitative analysis of the differences, to determine its nature, is random error or system error. Is given two boundaries, looking for a test statistic T, its distribution under the establishment of the H0 known.)

摘 要:针对茄子图像的灰度和颜色特点,利用MATLAB中丰富的图像处理函数,分别进行了色差分割和色调分割。在
色调分割中,采用了自动选取阈值的Otsu法。在去除残留噪音的处理中,采用标注的方法对二值图像的各连通区域进行面积
统计。保留最大面积的区域,从而使分割效果大大改善。利用多参数来衡量分割效果,使评价做到最大程度的客观、合理。(Based on the gray- level and color characteristics of eggp lant image, hue and color- difference segmentation were
conducted by using the rich image p rocessing functions embedded inMATLAB. The auto threshold- adap tivemethod ofOtsu operation
was specially used for hue segmentation. And upon the elimination of the residue noise, labelingmethod for statistical calculation was
introduced for the connected regions of the binary image. Themaximum areaswere p reserved to imp rove segmentation effects. In addi2
tion, multi- indiceswere app lied to assess the effect of segmentation, in order to get impersonal and reasonable assessment)

programming-in-matlab-2
This tutorial is intended for those who want to learn basics of MATLAB programming language.
Even with a limited knowledge of this language a beginning programmer can write his/her own
computer code for solving problems that are complex enough to be solved by other means.
Numerous examples included in this text should help a reader to learn quickly basic programming
tools of this language. Topics discussed include the m-files, inline functions, control flow,
relational and logical operators, strings, cell arrays, rounding numbers to integers and MATLAB
graphics.
