First,the distance ratio between within-class and between-class of each column of mixing matrix is computed by using a distance measurement.Then,for each class,the mixing matrix and independent components are re aligned by sort ascending according to the distance rate,and the columns of the weight matrix with smaller distance ratio and the corresponding features are reserved.Finally,the best feature set is selected by genetic algorithm from these foregoing feature vectors.

首先，使用一种距离度量来计算混合矩阵每一类的类内类间距离比；然后对每一类按该比值由小到大重新排列混合矩阵和独立分量，保留权重矩阵中类间类内距离比大的列，及其对应的特征向量；最后对这些特征向量使用遗传算法选择最优特征组。

The color moments of partitions are extracted from the L(superscript *)a(superscript *)b(superscript *) color space to solve the problem that the global color moment excludes the color space distribution, the edge orientation autocorrelogram is used to represent the shape content of an image, and the feature distance is respectively computed. The Guassian model is used to normalize the feature. Based on the normalized distance, the global similarity measure is obtained, and the retrieval precision is improved by the weight value adjustment.
