：提出一种快速有效推导不变矩的方法—三角函数生成法，并在此基础上描述了一种基于Hu 形状不变矩的
图像全局形状特征提取方法和算法。实验结果表明，使用这种算法提取的形状特征向量具有对平移、旋转和尺度变
化的不变性，适合于进行图像形状的检索。-The method of generating trigonometric function is suggested as a new efficient way to derive various moment
invariants，and it describes an extraction method of global shape feature of image based on Hu moment invariant and the
correlative algorithm. The experimental results illuminate that the shape features extracted by this approach is，rotation and
scaling to be which is translation rotation and soale invariance.
