DHT
- dht is very useful for bianxie chengxu
dct
- dct,dft,dht三种图像压缩变换之间的比较-DCT, dft, the dht three kinds of image compression transformation
DHT
- this source code and pdf are about the calculation of the discrete harhley transform
signalcompress
- 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 appr
transform-coding
- 对于变换编码的知识介绍，包括DCT,DHT,HARR,KLT,并对不同变换的性能做了对比-For transform coding knowledge presentation, including DCT, DHT, HARR, KLT, and the performance of different transform to do a comparison
DHT&FFT
- 详细介绍了离散哈特莱变换和傅里叶变换原理，以及两种变换之间的关系(discrete hartley transform and Fourier transform)
