normalized wavelet 中文意思是什麼
-
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
該演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徵值。 -
Normalized integral wavelet transform and its continuity
正規積分小波變換及其連續性 -
Image fusion based on wavelet transform is presented. by decomposing the images and mask signals with wavelet transform, wavelet coefficients and approximation coefficients at different scales are obtained. with the corresponding coefficients of normalized - mask signals as weighting functions, coefficients are combined in different resolution levels to reduce the effect of the seam
在基於小波變換的圖像融合中，將待融合圖像與mask信號採用小波分解，得到不同尺度下的小波系數與逼近系數，以歸一化mask信號的分解系數作為加權函數，在小波域的不同尺度融合對應系數，消除拼接縫的影響。 -
A face recognition algorithm based on improved bp neural network is proposed. first, wavelet transform is utilized to reduce both the dimension of face images and the data amount. then face images are normalized by illumination ratio image to overcome the influence of illumination variation
運用小波變換對人臉圖像進行降維，在減小數據量的同時保持圖像的基本信息;運用基於光照率圖像的方法對圖像進行光照校正，以改善光照變化對圖像質量的影響;運用改進的bp神經網路對不同光照條件下的人臉圖像進行識別。
