subpixel-image-registration

说明：  此为MATLAB课件，通俗易懂，能够快速把握MATLAB当中的重点和常用的知识点。主要设计到数值计算方面的知识。(matlab book)

数字水印lsb算法。matlab实现。空域算法，替换各像素最低位，不可见性较强，适用于脆弱水印。(Lsb watermarking algorithm. matlab implementation. Airspace algorithm, replacing the lowest level of each pixel, invisible and strong, suitable for fragile watermarking.)

说明：  shi kan，xuyaozhixinghoukanxiaoguo (shi kan, xuyaozhixinghoukanxiaoguo)

自己编的模拟退火算法源程序,希望对大家学习工作有帮助(Dynamic planning process in matlab)

numerical analysis, use for matrix condition number (numerical analysis,use for matrix condition number )

Not mine code, but very usefull!

Random embedding of an image in an image

电力系统中的有源电力滤波器仿真，其中的谐波检测方法是PQ法，谐波滤除的效果非常好。(Power system simulation of active power filter, where the harmonic detection method is PQ method, harmonic filtering effect is very good.)

说明：  跳频是按跳频序列随机改变一个信道所占有频道频率的技术。在GSM 系统中，可利用跳频技术频率分极和干扰分极的特点，改善网络质量。引入跳频技术，可保证在网络软拥塞不上升的情况下，频率复用度较小。(FH frequency hopping sequence is based on a random channel change in the country channel frequency technology. In the GSM system, can make use of frequency hopping technology sub-polar and polar characteristics of interference and improve network quality. The introduction of frequency-hopping technology to ensure that congestion in the network does not increase in the soft case, a smaller frequency reuse moment.)
