• 小波矩不变量 - 引用次数：9

  In consideration of the large feature dimensions of the wavelet moment invariants, we first choose a set of better features by combining divergence with Sequential Forward Selection and this can be an off-line computation process.

  3．针对小波矩不变量特征维数比较多的情况，本文采用结合离散度和顺序前进法的特征选择方法，先离线选取一组较优特征量。
