The present report outlines the design, implementation and performance of the application of Hough Transform (HT) to detect circles in arbitrary pictures. Detecting circles in arbitrary pictures involves a two step process in this project. First,

基于空间平滑技术的修正的music算法，第一个程序是正常的，第二个是修正的，其中，入射信号的方向已知-Modified music algorithm based on spatial smoothing techniques, the first procedure is normal, the second amendment, which, in the direction of the incident signal known
