离散傅立叶变换DFT和快速傅立叶变换FFT的比较(Discrete Fourier Transform and Fast Fourier Transform Comparison)

huffman coding and huffman decoding

Matlab中的基本数据类型是向量和矩阵，所以很自然地，信号处理工具箱中的信号也用向量或矩阵表示。列向量和行向量表示单通道信号，矩阵表示多通道信号，矩阵中的每一列表示一个通道。(The basic data types in Matlab is a vector and matrix, so naturally, Signal Processing Toolbox is also used in the signal vector or matrix. Column vector and row vector and single-channel signal, matrix multi-channel signal, a matrix each column represents a channel.)

读取计算机上的图片，图片格式的转换，并对二值化的图像进行radon变换，变换角度分别是0°、25°(Read the pictures on your computer, convert image format, and binarized image radon transform, transform angle are 0,25)

条带合成孔径雷达的点目标仿真程序，比较基础(Strip of synthetic aperture radar point target simulation program, a basis for comparison)

matlab制作的数字水印算法原程序，实现整个程序运行还行，共享给大家-jpeg of the Matlab Simulation, and the whole process has run OK, for everyone to share (matlab digital watermarking algorithm produced the original procedure, also realize the whole process to run line-sharing to the U.S.-jpeg of the Matlab Simulation, and the whole process has run OK, for everyone to share)
