卫星图片识别,利用圆谐展开的方法进行旋转不变识别，有图例，是好几个程序的结合-Satellite Photo identification, the use of circular harmonic approach rotation invariant recognition, a legend. Several of the integration process

功率谱分析，用于序列的周期识别。将一序列用不同周期的谐波分解,并用F检验进行周期检验。-Power spectrum analysis for identification of sequence cycles. One sequence will be different harmonic decomposition cycle and test cycle with F test.
