摘要
提出了基于综合鉴别函数和相移功率谱相减，具有旋转不变性的联合变换相关识别方法．该方法是将综合鉴别函数作为联合变换相关输入的参考物图象，结合相移功率谱相减方法，来获得具有识别目标的旋转不变性和高的相关识别率．
A new method for rotation invariant joint transform correlation,based on SDF and phase shift power subtracting,is presented. The method uses spatial SDF as the reference function of the displayed input scene and phase shift power spectrum subtraction,the proposed joint transform correlation is able to provide an image rotational inivariance and high correlation discrimination.In this paper,the simulation results are given.
