midterm1

对位图图像利用JPEG标准进行正交变换、量化、扫描从而达到压缩，同时解压显示其压缩图像。(Bitmap image using JPEG standard orthogonal transformation, quantization, scanning to achieve the compression, and decompression display the compressed image.)

卡尔曼滤波扩展程序代码，很好的程序，大家都来下载吧！赶紧的！(Extended Kalman filtering code, very good program, we have to download it! Hurry it!)

基于小波的多聚焦图像融合，使用了MATLAB语言(Image fusion by wavelet )

星形16QAM的编码与解码，主要是进码流进行编码，加噪声，显示画图，最后解码(Star 16QAM encoding and decoding, encoding and decoding of the star 16QAM star 16QAM encoding and decoding, encoding and decoding of the star 16QAM, star 16QAM encoding and decoding,)

说明：  最简单的模拟退火算法，自己编的小程序，用于优化问题，求全局最小值。(simmulated annealing (SA))

演示AR序列的特征值、自协方差函数和谱密度。程序是开放的，可以修改参数(Eigenvalues ​ ​ demo AR sequence autocovariance function and spectral density. The program is open, you can modify the parameters)

说明：  mppt模块，可以实现光伏发电系统光伏电池最大功率点跟踪，可以作为前端输入(Solar photovoltaic power generation simulink model, including battery, the function of maximum power point tracking and so on)

这是里面是岗萨雷斯（matlab）的第三章代码。(Fernando Gonzalez (matlab))

This code applies global histogram equalization on an input image with a view to improve its contrast ratio. The image is read, converted to grayscale and resized with the inbuilt function of MATLAB. The output is definitely a better contrast image as compared to the input

说明：  针对小流域设计洪水计算中，采用推理公式求解洪峰流量Qm及汇流时间τ的方法繁琐，查算精度较低等问题，提出用牛顿迭代法求解，该方法较原图解试算法收敛快，迭代次数少，计算速度快，精度可靠。计算实例表明，用简单迭代法与牛顿迭代法计算设计洪峰流量，其结果与图解试算法完全一致。()
