实现图像的对数极坐标变换，具有旋转不变性，可用于数字水印的抗几何攻击(achieving the right number of images Polar transform, with a rotating invariance, the digital watermark can be used against geometric attack)

用matlab设计FIR维纳滤波器 假设一个点目标在x，y平面上绕单位圆做圆周运动，由于外界干扰，其运动轨迹发生了偏移。其中，x方向的干扰为均值为0，方差为0.05的高斯噪声；y方向干扰为均值为0，方差为0.06的高斯噪声。用该滤波器处理观测信号，得到其最佳估计。(FIR Wiener filter design using matlab Suppose a point target in the x, y plane around the unit circle in a circular motion due to external interference, its trajectory shift occurred. Which, x the direction of the interference of mean 0 and variance of 0.05 Gaussian noise y direction of the disturbance is zero mean Gaussian noise variance 0.06. Observed with the filter processing signal, to get the best estimate.)

5个f语言有限差分正演程序，应用有限差分法在CPML边界条件下进行2D正演，前四个程序分别对应各向异性介质、各项同性2阶精度、各项同性4阶精度、双相介质4阶精度四种不同情况。最后一个是3D粘弹性介质的程序。(5 f language finite difference modeling, application of finite difference method under CPML boundary conditions 2D forward, the first four programs corresponding to anisotropic media, the isotropic second order accuracy, isotropic 4th order accuracy, double phases 4 order accuracy in four different situations. The last one is the program 3D viscoelastic medium.)

在实际应用着经常需要求解非线性整数规划或混合规划问题，该领域中的一种常用的算法是分支定界(branch and bound)算法，但是matlab工具箱中没有相关的函数。荷兰Groningen大学的Koert Kuipers编写的的BNB20工具箱可以用来求解一般非线性整数规划问题(In practice, frequent need to solve nonlinear integer programming or mixed programming problem, the area a popular algorithm is the branch and bound (branch and bound) algorithm, but the matlab toolbox functions are not related. Netherlands, Groningen University, prepared the BNB20 Koert Kuipers toolbox can be used to solve general nonlinear integer programming problem)
