数字图像处理1
说明: 任务 1 编写以两幅灰度图像为输入的 MATLAB 函数,计算下列图像差值度量:均方误
差(MSE)信噪比(SNR)峰值信噪比(PSNR)均值绝对误差(MAE)处理给定的测试图像“Lena”及其原始和后添加噪声形式。
任务 2 编写 MATLAB 函数,通过两种不同的方法将一幅灰度图像从原始大小下采样到
给定输出大小:a)直接消除像素,b)在消除像素之前进行初步图像平滑处理。用缩放系数 2:1、4:1、8:1 和 16:1 对给定的测试图像“Living.”进行处理。
任务 3 编写 MATLAB 函数,通过两种不同的方法将灰度图像从原始大小缩放到给定的
输出大小:a)像素重复使用上述方法将任务 2 中处理的图像缩放回原始大小。使用为任务 1 编写的 MATLAB 方法计算原始图像和缩放图像的 MSE 和 PSNR。将 MSE和 PSNR 分别作为大小缩减率的函数。定义对于相同的尺寸缩小比,收缩/缩放方法的组合提供最小 MSE 和最大 PSNR。
任务 5 编写 MATLAB 函数分别对测试图像“Fig0316(1)(top_.)”和“Fig0316(4)(._.)”执行直方图均衡。显示直方图均衡前后直方图的直方图。(task1

bcross
将断层剖面划分为一组网格,并以固定的事件数或固定的扫描半径,计算每个网格点处的b值。然后用色彩表示断层面上b值的分布情况,从而反应断层的应力积累情况,便于地震学家分析该断层是否存在发震的可能(This subroutine creates a grid with spacing dx,dy (in degreees). The size will be selected interactively or grids the entire cross section.
The b-value in each volume is computed around a grid point containing ni earthquakes or in between a certain radius. The standard deviation is calcualted either with the max. likelihood or by bootstrapping, when that box is checked.
If not, both options can be assigned by the additional run assignment.
Standard deviation of b-value in non-bootstrapping case is calculated from Aki-formula!)
