Matlab在图像处理与目标识别方面的应用实验程序示例。包括三个程序以及详细文档：一、染色体识别与统计，二、汽车牌照定位与字符识别，三、基于BP神经网络识别字符的简单实验(Matlab image processing and target recognition in the application of experimental procedures for example. Consists of three procedures, and detailed documentation: a, chromosome identification and statistics, two license plate location and character recognition, 3, based on BP neural network character of the simple experiment)

本程序设计的是咬尾编码的turbo码，用matlab编写。咬尾turbo码也即不需要拖尾比特，使得前后两个状态相同，译码采用修正的MAP译码算法。此文件为turbo码译码一般的MAP算法，程序中用作与咬尾turbo译码的对照(This program is designed to encode the turbo tail biting code, written with matlab. Tail biting turbo code that is not trailing bits to make the same before and after the two states, the MAP decoding using modified decoding algorithm. This document is a general MAP turbo decoding algorithm, and biting the end of the program for the control turbo decoding)

说明：  遗传算法中常用变异算子,开发语言为MATLABLE，希望对大家有所帮助(GA mutation operator used to develop language MATLABLE, we hope to help)

Thresholding is a key techniqur for the segmentation and edge detection. this program contained the matlab program for thresholding on the basis of energy entropy of an image.

地心坐标系下的经纬高坐标数据，转换为东北天坐标系下的坐标。输入为经纬高，单位为°。 matlab文件实现，调用函数名为：ECEFtoENV(Geocentric latitude and longitude coordinates of the high-coordinate data is converted to Northeast day coordinate system coordinates. Latitude and longitude input is high, the unit is.)

说明：  IIR filter implementation DFT

说明：  平均周期图法和平滑平均周期图法估计功率谱 从经典功率谱估计周期图法原理入手，从理论上分析了其存在的局限性，借助Welch算法对其进行修正。依靠Matlab强大的数值分析和信号处理能力进行实验!! 用周期图法和welch法分别估计了一下信号的功率谱密度。采样频率200Hz，时间序列长度2048，FFT数据点数2048。其中welch法使用hanning窗，窗口长度600．(Average periodogram and periodogram smoothing method to estimate the average power spectrum from the classical power spectrum estimation periodogram principle starting from the theoretical analysis of the limitations of its existence, with the Welch algorithm, amending them. Rely on the powerful Matlab numerical analysis and signal processing capabilities to experiment!! With periodogram and welch method were estimated signal power spectral density about. Sampling frequency of 200Hz, the time sequence length 2048, FFT data points 2048. Welch method which uses hanning window, the window length of 600.)
