经典傅立叶算法，可以自动生成测试数据，可实现一维以及二维傅立叶变换及反变换。-Classical Fourier algorithm, can automatically generate test data, enabling one-dimensional and two-dimensional Fourier transform and inverse transform.

自己写改进的经典算法，效果很好，可用于分割以及检测，精度高，效率高，可以直接执行，有简单的注释，可以作为算法的比较等，-Write your own improved classical algorithm works well and can be used segmentation and detection, high precision, high efficiency, can be executed directly, a simple note can be used as com
