1. 在No.1图形窗口中绘制 y=sin(x)在[0,2*pi]内的曲线。要求曲线的颜色为绿色,线型为 点划线,用*标示坐标点,在x轴的附近用 黑体 标注 ‘x轴’字样,在图形的上方加上标题 ‘正弦函数’,严格控制x,y轴分度相等,并开启网格。 2. 在No.2图形窗口中创建四个子窗口,在第一、二子窗口中用不同的方法同时绘制 y=x^2,y=-x^2,y=x^2*sin(x) 在[0,2*pi]内的曲线,并要给出标注 在第三个子窗口中绘制 三维曲线 3. 把No.3图形窗口分成五个子窗口,分别用plot3 mesh meshc meshz surf 来绘制 z=x*exp(-x^2-y^2) 在 -5=<x,y<=5 内的空间曲面图形,说明他们的区别,其中要求在用surf绘制的窗口内加入位置为[1,0.5,2]的光源,加入颜色标尺,采用spring色系

-The existence of numerous imaging modalities makes it possible to present different data present in different modalities together thus forming multimodal images. Component images forming multimodal images should be aligned, or registered so that all the data, coming from the different modalities, are displayed in proper locations. Mutual Information is the similarity measure used in this case for optimizing the two images. This method requires estimating joint histogram of the two images. The fusion of images is the process of combining two or more images into a single image retaining important features from each. The Discrete Wavelet Transform (DWT) has become an attractive tool for fusing multimodal images. In this work it has been used to segment the features of the input images to produce a region map. Features of each region are calculated and a region based approach is used to fuse the images in the wavelet domain.

The double-density DWT is an improvement upon the critically sampled DWT with important additional properties: (1) It employs one scaling function and two distinct wavelets, which are designed to be offset from one another by one half, (2) The double-density DWT is overcomplete by a factor of two, and (3) It is nearly shift-invariant. In two dimensions, this transform outperforms the standard DWT in terms of denoising however, there is room for improvement because not all of the wavelets are directional. That is, although the double-density DWT utilizes more wavelets, some lack a dominant spatial orientation, which prevents them from being able to isolate those directions.

①把settle定义成char型变量 ②settle=(settle>= A && settle <= B ) 写错了,改成(settle>= A && settle <= Z ) ③scanf函数后面加一句getchar()用来吸收回车键
