阵列信号的经典算法capon波束形成器，也就是capon算法，也可以用来估计波达方向（DOA）(Array signal of the classic capon beamforming algorithm is also is capon algorithm, also can be used to estimate the wave of direction (DOA) )

关于自适应控制，经过仿真证明可以用，而且比较准确，值得一看。(it is good )

说明：  在机器学习问题中，很多的算法归根到底就是在求解一个优化问题，然而我们的现实生活中也存在着很多的优化问题，例如道路上最优路径的选择，商品买卖中的最大利润的获取这些都是最优化的典型例子，前面也陆续地有一些具体的最优化的算法，如基本的梯度下降法，牛顿法以及启发式的优化算法(PSO,ABC等)。(In machine learning problems, many algorithms are in the final analysis to solve an optimization problem. However, in our real life, there are also many optimization problems, such as the choice of the optimal path on the road, the acquisition of the maximum profit in the sale of goods. These are typical examples of optimization. There are also some specific optimization algorithms, such as basic gradient Descent method, Newton method and heuristic optimization algorithm (PSO, ABC, etc.).)

A filter bank structure that can deal effectively with piecewise smooth images with smooth contours, was proposed by Minh N Do and Martin Vetterli. The resulting image expansion is a directional multiresolution analysis framework composed of contour segments, and thus is named contourlet. This will overcome the challenges of wavelet and curvelet transform. Contourlet transform is a double filter bank structure. It is implemented by the pyramidal directional filter bank (PDFB) which decomposes images into directional subbands at multiple scales. In terms of structure the contourlet transform is a cascade of a Laplacian Pyramid and a directional filter bank. In essence, it first use a wavelet-like transform for edge detection, and then a local directional transform for contour segment detection. The contourlet transform provides a sparse representation for two-dimensional piecewise smooth signals that resemble images.
