计算一幅图像的pnsr数值 只需要把要处理的图像直接输入就可以了 简单 方便(Calculation of numerical pnsr an image just to have to deal with the direct input of images can be a simple and convenient)

用fdatool设计一个50Hz陷波器，导出系数，编程，对原始信号signal.txt进行滤波。 本程序为Matlab程序。(50Hz with fdatool design a notch filter, export coefficient, programming, filtering the original signal signal.txt.)

利用重力剖面反演水平圆柱的边界及位置，程序抗干扰能力较差，模型计算加入噪音严重影响结果，但可作为算法参考并加以改进。(Tilt-Depth for gravity profile over horizontal cylinder)

采用FDTD方法对TM波在二维平面内的传播进行推进，另外，还对二维平面区域含有散射区情况进行了模拟。(FDTD method is used to propagate the propagation of TM wave in two-dimensional plane, and the two-dimensional plane region contains scattering region)
