Description: 如何在图像中加入某一固定snr的噪声？分类:matlab与图像处理
在利用matlab做一些自己算法的抗噪分析中，常常会遇到这个问题，matlab中的加噪函数是imnoise，里面的参数是噪声的均值，方差（高斯噪声）或者是感染概率（椒盐噪声），参数不能是snr值，但是很多国外的文章的噪声分析中都是用snr值来衡量加入噪声的程度的-how the image to a fixed snr noise? Categories : Matlab and image processing using Matlab to do some of his own anti-noise algorithm analysis, will often encounter this problem, which Matlab the noise function is imnoise. inside the parameters of the noise mean and variance (Gaussian noise) or the probability of infection (Impulse Noise) Parameter values can not be snr, But many foreign article noise analysis is used to measure the value snr joined the extent of noise Platform: |

Description: AffineTransformation computes and applies the geometric affine transformation to a 2-D image.
The program main functions are:
- Load Image: Load the image to be transformed.
- Transform Image: Computes the transformation matrix from the transformation parameters specified by the user, then it applies the transformation to the loaded image.
- Save Image: Save the transformed image.
- Quit: Exit the program.
The transformation parameters are specified by the user by editing the
values of the rotation, scale (x and y), and shear (x and y). The
translation is not icluded because it can be easily (normalized or) removed from the image by
subtracting the shape cetroid.
The affine matrix and the affinr transformation are computed using Matlab Image Processing Toolbox
functions: maketform and imtransform. So this program is only demonstrates and facilitates the computation and the applying of these functions to a 2-D image.

Description: 小波变换-图像融合的matlab代码~
图像融合实验。显微镜或照相机在某一次固定焦距下清晰成像的物距是一定的，即成像的物体只有一个层面是清晰而其它层面是模糊的，需要我们把各幅在不同焦距下的图像融合成一张图像，使得远近的物体都清晰。
设定好融合图像数、小波分解的层数、彩色图像的通道数等几个参数后，可对原图像进行融合。
本算法首先对彩色图像变成YIQ空间，对所有图像的各个颜色分量进行小波分解，然后在小波变换域上根据某种策略选取系数，最后做小波反变换和YIQ反变换即得结果图像。-Wavelet transform- image fusion matlab code to image fusion experiments. Microscope or camera in a fixed focal lengths clear imaging object distance is certain that the imaging of objects is only one level is clear and at other levels is vague, we need various pieces of different focal lengths, image fusion into an image, near and far objects in focus. Set fused image, wavelet decomposition of the number of layers, the number of channels of the color image and several other parameters, the original image fusion. The algorithm first color image into the YIQ space, each color component of the image wavelet decomposition, according to a strategy selection coefficient in the wavelet transform domain, and finally do the inverse wavelet transform and YIQ inverse transform to obtain the resulting image.
