针对多椭圆检测问题提出了一种快速随机检测算法。该算法利用在图像中随机采样到的一个边缘点和 局部搜索到的两个边缘点以及这三个点的邻域信息确定候选椭圆,再将候选椭圆变换为对应圆,通过确认真圆来确 认真椭圆。在确定候选椭圆时,最大限度地减少随机采样点数‰ 剔除更多的非椭圆点,降低了无效采样,减少了无效 计算。数值实验结果表明:该算法具有良好的鲁棒性,其检测速度比同类算法快(Ellipse detection problem for many a fast random detection algorithm. The algorithm uses random sampling in the image of an edge point and the local search to the two edge points, as well as the three-point neighborhood information to determine the candidate ellipse, and then transformed into the corresponding elliptical candidate won, through the identification of real yen to confirm really elliptical. In determining when a candidate ellipse, to minimize random sampling points ‰ remove more non-oval points, reducing invalid sampling, to reduce the calculation invalid. Numerical experimental results show that: the algorithm has good robustness, and its detection faster than similar algorithms quickly)

数字信号处理，用matlab来实现对信号的处理，这本书 是基础，手把手的教你(Digital signal processing, using matlab to achieve signal processing, this book is the basis, teach you hands-on)

线性调频信号是获得高分辨常用信号，文件是通过线性调频信号来进行脉冲压缩处理，获得高分辨。(Chirp signal is to obtain a high-resolution commonly used signal file chirp signal pulse compression processing to obtain high-resolution.)

自己编写的MATLAB函数，实现对图像的旋转。B是原图像，灰度或彩色，alpha是旋转角度（角度或弧度单位均可），A是旋转后图像。旋转后图像信息尽可能不损失。(I have written MATLAB function, to achieve image rotation. B is the original image, grayscale or color, alpha is the angle of rotation (degrees or radians per unit), A is rotated images. Rotation after the image information as possible without loss.)
