MainForPhaseAngle

代码说明：

  修改自pudn的fm_gui_v2.基于相位相关方法（傅里叶变化），可有效实现任意大小两图的位移、尺度变化、旋转量，并输出拼接结果(Modified pudn of fm_gui_v2. Based on phase correlation method (Fourier transform), which can effectively achieve the displacement of any size, the two figures, the scale changes, the amount of rotation, and outputs the result stitching)
