L egendre正交矩在模式识别、图像分析等许多领域有成功的应用 .然而 ,由于正交矩的复杂性 ,目前有关正交矩快速算法的研究很少 ,从而在一定程度上影响了它的应用 .对此 ,作者对 L egendre多项式进行了研究 ,获得了一些新的有效的性质 。
Legendre moments have been successfully used in pattern recognition and image analysis. However, due to its complexity, there exist few fast algorithms for computing Legendre moments, which limits its application. In this paper, some properties of Legendre polynomials have been investigated, they permit us to reduce significantly the computational complexity in the calculation of Legendre moments.
