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 to enhance t he efficiency and accuracy of ellip se detection in digital images.

说明：  实现机器视觉双目标定，三维重建等算法，具有很好地擦考价值( Robot with two cameras to switch recognition system. (Note that not binocular vision) and the reference used opencv1.0 cmv. )

MD5 algorithm can be directly called debugging no problem not subject to environmental restrictions

该源代码可以直接下载下来使用，而且是地地道道的对RGB图像进行分割，我已经测试通过了。(The source code can be directly downloaded to use, but also out-and-out on the RGB image partition, I have the test passed.)

粒子滤波算法的实现，其中重采样采用残差重采样算法。(Particle filter algorithm, in which the use of residual resampling resampling algorithm.)

Roberts算子，Prewitt算子，Sobel算子，Marr算子，Canny算子之一对输入图像 实现边缘检测，输出边缘图像并与matlab自带函数实现进行对比(Roberts operator, Prewitt operator, Sobel operator, Marr operator, Canny operator to achieve one of the input image edge detection, the output edge image and bring their own matlab function compared)

改进后的非线性各向异性扩散用于图像中的保边去噪，增加了二阶导数，是滤波效果更好(Improved nonlinear anisotropic diffusion for edge preserving image denoising, an increase of second derivative, is a better filtering effect)
