The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform. For Haar transform, the transformation matrix H contains the Haar basis functions hk(x). They are defined on a continuous, closed interval, x -[0, 1] for k = 0,1,2 ...,N -1 where N = 2n.( The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform.

在Matlab图像处理工具箱中的Phantom函数，可以产生Shepp－Logan的大脑图,利用RADON变换重建图像(In the Matlab Image Processing Toolbox functions in the Phantom can generate Shepp-Logan brain map, the use of RADON transform image reconstruction)

说明：  hough变换对圆的检测，h ough变换对圆的检测(hough transform circle test, h ough transform for circle detection)

本文深入研究了复杂调制信号MPSK、MQAM的倍号子类以及常用恒包络信 号OQPSK、or／4 QPSK、MSK的调制识别披本。在鳆种基本调制识别方法即基于特征提取的方法和基于最大似然的方法的纂础上采用四种算法分别对上述信号进行识别研究。(This article studies the complex modulation signals MPSK, MQAM number of times and the common sub-class of constant envelope signals OQPSK, or/4 QPSK, MSK modulation recognition of this disclosure. Abalone species in the basic modulation recognition method that is based on feature extraction methods and maximum likelihood methods based on the Article on the foundation of four algorithms to identify each of these signals.)

图像的放大缩小，其中缩小任意比例，放大整数比。在matlab的work路径中选择需要操作的图像，图像使用者自备。(Image Zoom, which reduce the arbitrary ratio to enlarge than integer. In matlab choose the path of work need to operate images, user-owned images.)
