摘要
等值滤波器、高斯滤波器、多项式样条滤波器和Meeretal滤波器是四种典型的用于产生多分辨率图像锥的低通滤波器．本文分析比较了它们的频域特性：抗混淆性和滤波性，并通过分析比较它们对图像信息损失程度的影响，指出用特性不同的滤波器产生的多分辨率图像锥的质量是不相同的，提出高质量的多分辨率图像锥将更加快速、准确和有效地分割图像．分割图像的实验结果证实了这一结论．
The average value filter, the Gaussian filter, the polynomial spline filter and the Meer etal filter are four typical low-pass ones used to generate multiresolution pyramids. In this paper,their frequency characteristics, the antialiasing characteristic and the filtering characteristic, areanalyzed and compared. Their effects on image information loss are compared. It is indicated that thequality of pyramids generated by filters with different characteristics are different. The idea isproposed that image segmentation can be achieved much precisely, effectively and fast based on goodquality pyramid, then image segmentation experiments are tested and the idea is verified.
