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 该方法直接在二维空间上由db6小波包基对笔迹纹理实施3尺度小波包分解,再在由以香农熵为代价函数提取得到的15个小波包最好基处对分解系数实行重构。
