It is ingrained in many men that masculine identity means holding back the tears except during times of extreme grief. Although women hav 阅读全文

摘要： 在C++中，读入一幅图像使用语句如下，读入的图像像素为0-255之间的某一整数：Mat disp_image = imread(path,1);其中图像每个像素的RGB值是用3元素向量来存储（B,G,R）的，某一像素点的RGB值读取方式如下：Vec3b& mp = disp_image.at<Vec3b>(j, i); //C++用向量存储像素值double B = mp.val[0]; double G = mp.val[1];double R = mp.val[2];在matlab中，读入一幅图像并转换为double型使用语句如下，读入的图像像素在0-1之... 阅读全文

摘要： 1.最小二乘拟合最小二乘拟合是一种数学上的近似和优化，利用已知的数据得出一条直线或者曲线，使之在坐标系上与已知数据之间的距离的平方和最小。2.RANSAC算法参见王荣先老师的博文 http://www.cnblogs.com/xrwang/archive/2011/03/09/ransac-1.html3，直线拟合建立模型时利用直线的一般方程AX+BY+C=0，随机选取两点构建直线模型，计算每个点到此直线的TLS（Total Least Square），TLS小于一定阈值时的点为符合模型的点，点数最多时的模型即为最佳直线模型。再根据此时的直线参数画出最终拟合直线。4.椭圆拟合建立模型时利用椭圆 阅读全文

摘要： openCv学习笔记（二）—cv::Mat学习由于在写上一篇图像的数据结构时，发现自己只知道CvMat,竟然还有Mat数据结构，真是无知了，看了这么多程序，貌似没有看到这个结构。有可能那些程序都是些老版本的例子，这是在2.0以后加上的，所以我也得紧跟呀！以下是自己的学习心得。。。。一、Mat简介 在2001年刚刚出现的时候，OpenCV基于 C 语言接口而建。为了在内存（memory）中存放图像，当时采用名为 IplImage 的C语言结构体，时至今日这仍出现在大多数的旧版教程和教学材料。但这种方法必须接受C语言所有的不足，这其中最大的不足要数手动内存管理，其依据是用户要为开辟和销毁内存负责。 阅读全文
