THis contains routing algorithms and certain cipher techniques using Matlab

A Costas loop is a phase-locked loop used for carrier phase recovery from suppressed-carrier modulation signals, such as from double-sideband suppressed carrier signals. It was invented by John P. Costas at General Electric in the 1950s. Its invention was described as having had "a profound effect on modern digital communications".

求图像的信噪比函数及峰值信噪比函数 很有用(Demand function is useful for image signal to noise ratio)

本文在Matlab7．5下面实现了fisherface算法，选用的人脸库是ORL，其中有40 人，每人有10幅不同的人脸图像。本文选取了每人9幅作为训练(1幅作为测 试)，图像大小为112x92。(In this paper, the following Matlab7.5 realized fisherface algorithm, selection of face database is ORL, in which 40 people, each person will have 10 different people face image. This article is selected as a training per nine (one as a test), image size is 112x92.)

利用参数辨识法提取相关对准参数，从而估计出陀螺漂移和数学平台偏角并进行补偿。仿真结果表明，开路罗经法对准具有较高的对准精度、较好的快速性，能够满足捷联惯导系统在静基座下实现自对准的要求。(Expressions of mathematical platform misalignment angles of the open-loop algorithm are derived and parameter identification method is used to pick-up the corresponding coefficients from angle measurements in order to identify and compensate gyro drifts and platform misalignment．The simulation results show that the open circuit gyrocompass alignment of SINS can all meet the requirement of SINS initial alignment with high accuracy and quick reaction on static base. thus can meet the high-precision alignment requirement of carrier based inertial navigation system on swinging base． )

说明：  这里边提供了一个matlab实现的图像配准的算法. 供大家参考,方便学习研究之用.(here is the realization of a Matlab image registration algorithm. For your reference, facilitate learning research.)
