基于三阶自相关的图象不变性变换研究

The Study of 3D Data Model and Animation Display of the Body Meridians and Collaterals

二维图象的三阶自相关函数是关于图象信息的全描述，它具有图象平移的不变性和ＡＧＮ噪声不敏感性。本文根据三阶自相关函数两个偏置矢量的分布特征，对偏置矢量所构成的矢量三角形，依据三角形之间的相似性来描述其分布，推导出表征三角形形状类型的三阶自相关函数。通过对该三阶自相关函数幅度变化因子进行对数坐标变换及ＦＦＴ变换，建立了对图象平移、旋转和伸缩变化具有不变性的特征变换集合。仿真实验结果表明，特征变换集合具有三种不变性。

This paper discusses the method of getting bodys 3D space data,a Jingluo(meridians and collaterals)data model based on homogeneous coordinate transform is purposed ,which not only solve the problems of animation demonstration and transparent reiteration of Jingluo and acupoints ,but also lay the foundation for advanced research on Jingluo by mathematics or making overall observaton.The method of displaying Targa image and FLI animation under Windows environment is purposed after analyzing their formats.
