Description: 本程序利用奇异值分解对3通道彩色图像进行压缩分解，具体步骤如下：
压缩过程：
1. 选取子图像大小K值，把图像分解成M×M个子图像，IMG(s),s=1,2,…, M2，其中M=N/K，原始图像IMG大小为N×N。
2. 计算这M2个子图像的平均值average，对每幅子图像减去均值图像得到新图像。
3. 计算相关矩阵R，其元素定义为 。
4. 计算R的特征值与特征向量，计算每幅子图像与最大特征向量的内积，便得到编码，即压缩后的图像。
-This procedure using singular value decomposition of 3-channel color image compression decomposition, concrete steps are as follows: compression process: 1. Select the sub-image size K value, the image is decomposed into M × M sub-image, IMG (s), s = 1, 2, ..., M2, in which M = N/K, the original image IMG size N × N. 2. M2 calculate the average of sub-image average, for each sub-image minus the new images mean images. 3. Calculation of correlation matrix R, defined as its elements. 4. Calculation of the characteristics of R value and eigenvector calculated each sub-image with the largest eigenvector of the inner product, they will have to code, that is, the compressed images.

Description: In this project, we intend to segment natural images by combing colour and texture information. For this we will be using an unsupervised image segmentation framework (referred to as CTex) that is based on the adaptive inclusion of color and texture in the process of data partition. It is new formulation for the extraction of color features that will evaluate the input image in a multispace color representation. To achieve this, we will be using the opponent characteristics of the RGB and YIQ color spaces where the key component will be the inclusion of the Self Organizing Map (SOM) network in the computation of the dominant colors and estimation of the optimal number of clusters in the image. The texture features will be computed using a multichannel texture decomposition scheme based on Gabor filtering. Platform: |

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.
