基于椭圆外接矩形的椭圆识别，画出几何图形的外切矩形和此外接矩形的内切椭圆，将画出的内切椭圆与几何图形进行比较！判断原几何图形是否为椭圆！-Ellipse shape detection base on the enclosing rectangle identification method

基于霍夫变换的外形检测算法的实现，包括图像读取与显示、彩色图像转化为灰度图、灰度图二值化、膨胀腐蚀、图像轮廓提取、线性图形检测以及椭圆检测-Shape detection algorithm based on Hough transform implementation, including the image read and display color images into grayscale, grayscale binary and expansion corrosion image

椭圆检测。利用霍夫变换的原理实现椭圆的检测，并在图中标记出来，可用于方向盘的检测。-Ellipse detection. Using the principle of detecting the implementation of elliptic Hof transform, and marked in the graph, can be used to detect the steering wheel.
