Chapter 1 briefs the relation between invariance and computer vision and summarizes the research and application of invariance in computer vision. Chapter 2 first derives the transformations of three camera models, then makes the correpondences between the models and three typical geometrical transformation groups by analysing the transformations respectively. The correspondences supply the theoretical basis for applying geometrical invariants to resolve the problems of computer vision. In Chapter 3, we describe the geometrical invariant theory and prove some geometrical invariants of coplanar points, lines or conics by algebraic method. In order to use the invariants of conic pairs to describe general 2D shapes, we discuss the perspectively invariant representation of planar curves using conies in detail. A system consisted of two TMS320C25 and based on moment invariants is introduced in Chapter 5. The system can recognize more than 30 different shapes of object model or more than 10 plane models with similar shape in real time.
第一章简述了不变性与计算机视觉的关系,以及计算机视觉中的不变性研究和应用概况;第二章推导了计算机视觉中常用三种投影模型的变换关系,通过对这三种变换关系的分析,分别建立了这三种投影模型和几何学中的三种变换群之间的一一对应关系,为几何不变性在计算机视觉中的应用提供了理论基础;在第三章中,我们介绍了几何不变性的理论,并且用代数方法证明了共面点、直线、二次曲线的几何不变量和射影不变量;为了把二次曲线的不变量用于一般二维形状描述,在第四章中我们详细地讨论了用二次曲线实现一般平面曲线的透视不变性表示的方法;第五章介绍了用两片TMS320C25构成的、基于不变矩形特征的运动目标实时识别系统。
