HU不变矩程序代码很多,但是没找到一个完整准确的代码。本人对其中的某些代码修正后,和matlab计算结果进行比较,结果是一致的。本程序没有利用Opencv计算Hu矩的函数,好像opencv计算的M03和M30应该对调,否则,和matlab计算不一样!对旋转、缩放的图像进行测试,HU矩也是一样的,不信可以利用提供的图片对比一下。由于HU矩比较小,程序对HU矩取对数便于查看比较。总之,程序绝对安全可靠,可直接调用。,HU moment invariants code a lot, but could

Images passed to your application are not always of the same size as your
templates. To compare them you might need to up scale or down scale them to
the template size. It is preferred that when comparing you check the size of the

本程序主要四大功能特点:
1、继承了 YUVViewer 可以同时打开多窗口的特点;
2、继承了 Elecard YUV Viewer 可以进行两幅图像对比的特点;
3、增加了宏块信息显示功能;
4、增加了两图对比时同步帧跳转功能:
例如对于错误码流,不同的错误隐藏算法可能造成解码序列长度不同,这时要比较两个序列就很不方便。而该功能正是为了解决这个问题,即以另一序列的显示图像为标准,在当前序列中寻找与其完全相同的图像。 -Four main features

为了研究植物的生长规律,应用数字摄影图像处理法对山楂叶面积进行无损测量,该方法采用数码相机在田间获取山楂叶子的数字图像,对所拍图像进行背景去除、二值化及中值滤波处理,然后利用Matlab软件编程.快速计算出叶子的面积。把这一面积同常用的叶纸称重法所测面积进行比较.结果基本相同,由此可见,数字摄影图像法测量叶面积,具有简单、准确、方便快捷的特点.这对数字农业的植物信息快速采集和利用具有重要的意义。 -
