The method directly executes wavelet packet decomposition of handwriting texture using wavelet packet basis db6 at scaling 3 in 2d space , then reconstructs the decomposition coefficient of 15 wavelet packet best basis which are took by shannon entropy cost function 該方法直接在二維空間上由db6小波包基對筆跡紋理實施3尺度小波包分解,再在由以香農(nóng)熵為代價函數(shù)提取得到的15個小波包最好基處對分解系數(shù)實行重構。
