所谓跳频，比较确切的意思是：用一定码序列进行选择的多频率频移键控。(The so-called frequency hopping, the exact meaning is: a certain code sequence selected frequency to frequency shift keying.)

采用Gabor_Palm函数提取掌纹图像的能量特征，并将得到的结果果分块，分别计算每块的均值和方差作为特征向量。特征向量的长度为160. (Gabor_Palm function using the energy extracted palmprint image features, and will be the result of ssub-blocks, each block were calculated the mean and variance as the feature vector. The length of fea )
