MATLAB编写实现图像几何校正的程序，根据靶图将tiger图像从鱼眼形变恢复(MATLAB for Image geometry correction preparation procedures, in accordance with the target map to tiger fish-eye images from the restoration of deformation)

自适应滤波，LMS算法，matlab编写，线谱提取(Adaptive filtering, LMS algorithm, matlab prepared line spectrum extraction)

The proposed filter is able to suppress high-density of salt-and-pepper noise, at the same time preserving fine image details, edges and textures well.

用HOUGH检测直线的时候是两个未知量,因为轴半径和相角可以确定一条直 线，在HOUGH域出现累计最大点就可能是原域中的直线。现在回到圆的检测 上来，确定一个圆需要什么：X坐标，Y坐标，半径三个未知量吧，好了，现在， 你做一个三维空间的HOUGH域，以这三个未知量作为三个轴，现在按照一定步长 进行三重循环，在最内层循环是这样的，X,Y 确定，以不同的半径进行搜索，如 果你的X,Y刚好就是实际图像的X,Y处，半径又搜索到实际真实的半径(The HOUGH detect straight when two unknown amount of axis radius and phase angle can be determined in a straight line, in the HOUGH domain cumulative maximum point may be the straight line of the original domain. Now back to the circle detection up to determine what a circle: X coordinate, Y coordinate, radius three unknowns, now, you do the HOUGH domain of a three-dimensional space, three to three unknown quantity as axis, in accordance with a certain step size triple loop, is such that in the innermost loop, X, and Y determined search for a different radius, If you X, Y, exactly is the actual image of the X, Y, at the radius radius of the search to the actual real)

用matlab实现矩阵的高斯分解，A=LU,A为下三角，U为上三角(Gauss decomposition)

反距离权重插值算法的matlab实现，简单易懂的算法(IDW interpolation algorithm matlab realize, straightforward algorithm)

利用blackman窗设计Ⅳ型数字带通滤波器MATLAB实现代码。(Blackman window design IV digital band-pass filter MATLAB code.)

这是一个非常重要的而又简单的程序，是书上常用和数学建模的好帮手(nice work )

说明：  实现了用超声波测量以及形成图像 对相关信号进行模拟仿真(Achieved the formation of images using ultrasound measurements, and simulation of the relevant signals)
