基于非解析正交矩的图像分析

Image Analysis Based on Non-Analytic Orthogonal Moments

为进一步提高正交矩的图像特征表达能力,根据零点采样原理,认为权函数是影响正交多项式零点分布的关键因素,采用正交化准则与数值方法相结合的手段求取非解析正交多项式,从而构造高性能的非解析正交矩,实验验证表明该方法是有效的。

In order ry of zero samplin to enhance the feature extraction capabilities of orthogonal moments, based on the theo g, we think that the power is the key factor in influencing the zero distribution of orthog onal polynomials. And the orthogonality criterion and numerical algorithm are used to resolve non-analytic orthogonal polynomials and construct the non-analytic orthogonal moments. The experimental results show that the proposed moments have superior performance.
