High accuracy optical flow using a theory for warping(The files optical_flow_brox.m and optical_flow_sand.m are the files you need to run. optical_flow_brox.m implements the traditional algorithm. Just replace the first lines where images are read, with your image, and start the process. optical_flow_sand.m implements a variant presented in CVPR 2006. Again just replace the lines "img1 = imread( ... )" and "img2 = imread( ... )" with your images and the rest is automatic. The variable num_levels controls the number of images in the laplacian pyramid to be constructed. Change it to suit your convenience.)

this is a code of lpc decoder

matlab下的轮廓跟踪算法，获得边界数值数组和一些测量位置和边界。(get border as numeric array and a number of measurements of a spot and a border)

说明：  合成矩阵,将各列最大元素提出来，记录原来位置，形成新矩阵(Synthesis of matrix, the largest element of the proposed column, record the original position to form a new matrix)

hough变换用于直线的检测，适用于计算机视觉的初学者，简单容易理解。。。(hough transform for line detection, computer vision for beginners, easy to understand. . .)

二用户CDMA系统，信道为加性高斯信道，使用BPSK调制，15位M序列扩频，可以正确解扩解调。 输出为2用户的基带信号、扩频信号、PSK调制信号、解调信号的时域和频域特性，给出两个用户分别的误码率。 (Second, the user CDMA system, channel for the additive Gaussian channel, using BPSK modulation, 15 M Sequence Spread Spectrum, you can correct demodulation despreading. Output of 2 user' s baseband signal, spread spectrum signal, PSK signal modulation, demodulation signal time domain and frequency domain characteristics of the two users are given the bit error rate, respectively.)

包括四个.m文件，采用16QAM调制，添加循环前缀与后缀，加窗处理，防震性能很好。(Including four. M files using 16QAM modulation, add cyclic prefix and suffix, window treatment.)
