Description: MATLAB中画椭圆的自定义函数：ellipse，用后才会发现这个函数的强大功能！
在ellipse之函数当中，其输入之变数分别如下：
-ra 椭圆之长轴半径，可为列矩阵，若为列矩阵时，代表可同时绘制许多椭圆。
-rb 椭圆之矩轴半径，可为列矩阵，如ra。
-ang 水平轴之倾斜角，以弧度表示。可为列矩阵，但ra、rb、ang三者之矩阵数应相同。
-x0,y0 圆心之座标，可为矩阵，若为矩阵时，代表可同时绘制许多不同圆心位置之椭圆。
-C 椭圆线之颜色
-Nb 绘椭圆时所用之点数。-MATLAB in the oval painting custom function: ellipse, will be found after using the power of this function! Ellipse of the function in which its input variables are as follows:-ra ellipse of major axis radius for the column matrix, if for the column matrix, a representative may at the same time drawing many elliptical. oval-rb-axis radius of the moment for column matrices, such as ra.-ang horizontal axis of the tilt angle to radians. Matrix for the column, but ra, rb, ang among several of the matrix should be the same.-x0, y0 the coordinates of the center for the matrix, if for the matrix, a representative may at the same time drawing a number of different oval center location.-C elliptic line color-Nb painted oval of points used.

Description: 为了提高数字图像中椭圆检测的效率和准确性,提出了一个基于最小二乘法的改进的随机椭圆检测算法.
该算法随机选取图像中的3 个边缘点,在以这3 个点为中心的窗口内,从边缘点中拟合出可能椭圆,并通过随机选
取的第4 个边缘点来确认可能椭圆. 利用直接最小二乘法椭圆拟合的特性,引入可能椭圆边缘点收集和椭圆重新
拟合的迭代过程来提取最终的椭圆参数. 通过对含有不同噪声的仿真图片和包括残缺椭圆的实际图片的实验表
明,新算法的改进是有效的. 与原算法相比,新算法降低了对参数的依赖性,提高了检测的速度、稳定性和准确性,
同时保留了原算法的抗噪声能力.-: An imp roved randomized ellip se detection algorit hm based on least square approach was proposed
