VDI_2230_calculation

基于MATLAB的霍夫曼编码。包括MATLAB界面下生成的结果图。程序较C语言易懂，由于在MATLAB下实现，程序简洁。(Huffman coding based on MATLAB. Including the MATLAB interface to generate the results of Fig. Procedures easy to understand language than C, because under MATLAB, the program simple.)

卡尔曼滤波程序代码，包括EKF UKF CKF(EKF UKF CKF)

此程序为数学形态学中的膨胀运算，用于将图像编码充满整幅图像(This program is the expansion of operations in mathematical morphology, image coding for the entire image is full of)

用于快速处理压缩感知的程序。输入原向量及其长度即可得出压缩前向量。（需要使用pdco.m文件。）(For fast processing of compressed sensing program. Enter the original vector and its length can be derived before compression vector. (Need to use pdco.m file.))

这几个程序可以实现加窗后对信号滤波，包括凯泽窗，汉明窗，矩形窗(This several programs can realize add window to signal after filtering, including the Kaiser window, han Ming window, rectangular window )
