该融合策略首先在区域能量的基础上引入区域梯度，然后根据匹配度的类型和测量值进行小波低频系数的选取。
It is performed by introducing the local gradient into local energy and then selecting the low frequency coefficients according to the type and the vale of match measures.
颜色特征采用整数小波低频系数矩阵中环形区域的F -范数，纹理特征则采用高频部分的能量比值。
The circular region F-norms in low frequency band of wavelet transform is used as color feature of the image and the energy ratio of high frequency band is used to form texture descriptor.
