利用图像的不变矩特征进行目标识别是一种有效的方法。通过比较Hu矩、 仿射不变矩和小波不变矩的特点和适用条件，提出了一种运用部分Hu矩、仿射矩和小波矩组合来识别舰船图像目 标的方法。仿真实验结果表明，该组合矩对于提高舰船图像目标的识别率是有效的。

It is an effective method to use the invariant moment features for target recognition. By comparing the features and applicable conditions of the Hu moment, affine invariant moment and wavelet invariant moment, a method in which the combination of partial Hu moment, affine invariant moment and wavelet invariant moment is used to recognize ship image targets is proposed. The simulation result shows that the combined moments are effective for the improvement of the recognition of ship image targets.
