旋转和尺寸变化的图象的相关识别

Rotation and scale invariant pattern recognition

利用光栅矢量法设计旋转和尺寸不变图象识别所需的位相片，进一步阐述了这种方法的一些特点，并用基尔霍夫衍射积分验证了位相片的变换效果的确是理想的。

This paper discribes using the new method of grating vector for designing the phase element for rotation and scale invariant pattern recognition, discusses the peculiarity of this method.The Kirchhof integral used to test the results of this design,which proved that the transform effect of the elements is ideal indeed.
