The polar coordinate and Fast Fourier Transform(FFT) method are introduced to determine the invariant features of the transformed matrix. The targets are classified and recognized by calculating the same correlation of the characteristic matrix and the template features matrix.

利用多特征融合方法，从原始图像中提取待识别目标实现维数压缩任务；引入极坐标变换和快速傅里叶变换相结合的方法，确定变换后的不变特征矩阵；通过计算不变特征矩阵和模板特征矩阵的相关性对目标进行分类识别。
