(一)菜单设计 一.建立用户菜单 1.概况: 用户菜单一般含有一级菜单和二级菜单,乃至多级菜单.每一级菜单又包含多个菜单项.建立菜单可以使用uimenu函数. 2.uimenu函数调用: %建立一级菜单的函数调用: 一级菜单句柄=uimenu(图形窗口句柄,属性名1,属性值1,属性名2,属性值2,--); %建立一级菜单需给出图形窗口的句柄值. %如果省略句柄值,MATLAB就在当前图形窗口中建立这个菜单项. %如果当前没有图形窗口,则自动打开一个图形窗口. %建立子菜单项的函数调用: 子菜单项…

BRIEF特征全称:Binary Robust Independent Elementary Features.是一种能够快速计算图像特征描述符的方法,同样能够降低特征匹配的时间. 算法计算步骤如下: 1.首先对一张图像计算其特征点,这里就用matlab自带的harris角点检测了,harris代码细节可以参考这一篇博客. 2.对图像进行高斯滤波,这里选用9*9矩阵,主要是为了去除随机噪点. 3.以特征点为中心,取SxS的邻域窗口.在窗口内随机选取一对(两个)点,比较二者像素的大小,进行如下二进…
