这种方法一方面将像素的灰度值分散，可以分辨图象中比较细节的内容；另一方面，将图 象的灰度变化控制在一定范围之内，抑制了噪声的产生，较大程度上地保留了原始图象的亮度．(This approach on the one hand spread the pixel gray value, the more details you can identify the contents of the image the other hand, the image gray scale control in a certain range, suppress noise generation, a greater degree preserved on the original image brightness.)

用于求解光学传输过程中的波前畸变，对光学分析起到非常关键的作用(heat depoization)

The principle of Huffman coding is (roughly) to replace symbols in the original data (in your case the value of each pixel of the image) by a numeric code that is attributed according to the probability of the symbol. The most probable (i.e. the most common) symbol will be replaced by shorter codes in order to realize a compression of the data.

说明：  采用不同的方法对HRV信号进行功率谱估计。选择矩形窗，汉宁窗，汉明窗，Blackman窗(Using different methods of HRV signal power spectrum estimation.Select the rectangular window and hanning window, hamming window and Blackman window)
