说明：  Matlab for VQ 向量量化編碼(Matlab for VQ vector quantization)

说明：  信号处理 是经验小波分解， 能够有效的分解信号，提取故障特征(Signal processing is empirical wavelet decomposition, which can effectively decompose signals and extract fault features)

可在matlab上运行输出的Pt1000铂热敏电阻的分度表，电子表格格式的。(Can be run in matlab output Pt1000 platinum thermistor sub-degree table, spreadsheet format.)

此程式為使用背景影像相減法在MATLAB軟體環下的實作程式,此程式運行需要一個解析度為320*240的.AVI格式的影片檔,並且須修改程式碼中影片放置的指定資料夾路徑。(This program for the use of background subtraction imaging software in the MATLAB Central under the program to implement, run this program requires a resolution of 320* 240' s. AVI format video files, and code should be amended to place the specified video folder path .)

Estimates the power spectral densities (PSDs) using the ML-based empirical Bayes method for deciding the diagonal loading.

matlab的高阶谱工具箱 内有说明 有兴趣的朋友可以参考(matlab toolbox containing high-level spectrum shows friends who are interested can refer to the)

给出了信号压缩通常的变换-量化-编码函数。DHT函数为离散DHT变换，是FFT变换的近似，其正反变换相同，克服了FFT复系数不利于存储的缺点。LLMAX函数给出了某x序列在固定比特下的最佳量化输出。熵编码函数为霍夫曼编码。(Gives the signal compression usually transform- quantitative- coding function. DHT DHT discrete transform function, the FFT transform approximation, the same positive and negative transformation, overcoming complex FFT coefficient is not conducive to storage shortcomings. LLMAX function x is given a fixed bit sequence in the optimum quantized output. Entropy coding function as Huffman coding.)
