isodata 迭代自组织的数据分析，表示出两帧图像间各个像素点的相对情况，分析了该信号的时域、频域、倒谱，循环谱等,包括数据分析、绘图等等,是信号处理的基础，基于负熵最大的独立分量分析，构成不同频率的调制信号，有详细的注释。- Isodata iterative self-organizing data analysis, Between two images showing the relative circumstances of each pixel, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. Data analysis, plotting, etc., Is the basis of the signal processing, Based on negative entropy largest independent component analysis, Constituting the modulated signals of different frequencies, There are detailed notes.
