图像相似度计算方法集

说明：  基于信息熵进行图像质量评价，评价图像质量好坏。流程简单易于操作(Image quality evaluation based on information entropy)

说明：  基于小波的图像质量评价方法，具有一定借鉴意义。(Wavelet-based image quality assessment method, with some reference.)

JPEG2000自己编写的代码，与标准版有所不同，里面有详细注释，可以运行(Own code JPEG2000 Standard Edition is different, there are detailed notes, you can run)

改进分水岭算法，详细注解标在m文件内了，希望对大家有用(Improved watershed algorithm and hope for all of us)

对特征选择与提取进行介绍，及几个特征提取方法简介(For feature selection and extraction are introduced, and several feature extraction methods Introduction)

此FCM-PSO是对于FCM的改进，用于图像分割，效果好。(it is an improvement on FCM for image segmentation)

说明：  分水岭算法是一种图像区域分割法，在分割的过程中，它会把跟临近像素间的相似性作为重要的参考依据，从而将在空间位置上相近并且灰度值相近的像素点互相连接起来构成一个封闭的轮廓，封闭性是分水岭算法的一个重要特征。本示例适用于二维和三维图像，计算分水岭变换并将结果标签矩阵显示为RGB图像。 分水岭算法是一种图像区域分割法，在分割的过程中，它会把跟临近像素间的相似性作为重要的参考依据，从而将在空间位置上相近并且灰度值相近的像素点互相连接起来构成一个封闭的轮廓，封闭性是分水岭算法的一个重要特征。本示例适用于二维和三维图像，计算分水岭变换并将结果标签矩阵显示为RGB图像。(The watershed algorithm is an image region segmentation method. In the segmentation process, it will use the similarity with neighboring pixels as an important reference basis, so as to connect pixels that are close in space and have similar gray values to each other. Forming a closed contour, closedness is an important feature of the watershed algorithm. This example applies to 2D and 3D images, calculates the watershed transformation and displays the resulting label matrix as an RGB image.)

PDF417条码定位与检测，视频课程作业，很好的定位了条码而且将其旋转到正方向(PDF417 bar code location and detection, video course work, a good positioning of the bar code and will rotate to the positive direction of its)

说明：  共享主成份尺度不变变换PCA-SIFT代码，用于SAR图像配准，希望对各位雷达爱好者和SAR工作者有用！(Principle component analysis, PCA- Scale invariant feature transform-SIFT used for SAR processing. )

opengl图形实现，非调用函数直接构图，初级参考学习不错(opengl graphic realization, non-call direct mapping function, the primary reference to learn good)
