The experts in engineering , especially in engineering expect that the compact support wavelets are real , orthogonal and symmetric . in fact , no such a wavelet , except the wavelet haar , is found 工程界使用的小波一般而言是實值的緊支正交對稱或反對稱的,這有很多好處,尤其在數字圖像的邊界處理中。
Secondly , in the feature extraction stage , haar 2 - d wavelet transform is used in each band of the normalized image . the mean values and variances of the coefficients of 7 main wavelet channels are extracted as features 該算法通過對歸一化處理后虹膜圖像的各個小分割區域進行二維小波變換,提取出主要小波通道的小波系數均值和方差作為特征值。
