全套的DCT域数字水印源代码（本人毕业设计成果）内容包括：水印嵌入，水印检测，攻击实验以测试鲁棒性，重要参数计算。希望对做数字水印的XDJM有所帮助。(complete DCT digital watermarking source code (I graduated design results) include : watermark embedding, Watermark detection, attack experiment to test the robustness, an important parameter calculation. Want to do digital watermarking Wilson help.)

程序来自《现代通信系统－使用matlab》英文版 已经调通！并加上了注释。 希望对大家有帮助4(fpga)

An alternative to Matlab s HIST, function HISTW prevents extreme values in top and bottom percentiles of an input vector affecting the histogram s scaling, obscuring location and shape of the distribution s main mass. Limits of x and y (maximum only) axes can be set, and a marker line drawn at given x position. In contrast to HIST, bin size can be explicitly specified, and relative, rather than absolute, frequencies are plotted.

Aiming at determining the satellite attitude precisely，the gyros bias and m isa lignment were compensated in time by using the quaternion of star-sensor and extended Kalm an filter．The related module of the filter was derived．The theoretic accuracy of the algorithm was acquired from the numerical simulation． The effects of the star-senso r misalignment on attitude determination were analyzed at last．
