项目摘要

The research introduces a novel axial representation of two- and three-dimensional shapes that implements Binford's original notion of ribbons and generalized cylinders for generic objects. Unlike current representation schemes based on generalized cylinders, which use much more restrictive parametric models such as straight homogeneous generalized cylinders, and are thus limited to instances of these models, this representation can be constructed for arbitrary objects by computing the one- dimensional valleys of a multi-dimensional height field defined by the area of intersection of the object and a parameterized plane. The main objectives of this research are: (1) to give a data-driven, operational definition of ribbons and generalized cylinders that yields practical algorithms for constructing the description of an arbitrary shape from two- or three-dimensional data; (2) to establish the formal properties of the representation with the aims of assessing its scope and developing rigorous algorithms for detecting generalized cylinder projections in images; and (3) to develop a principled approach to part decomposition and use the constructed part-whole hierarchies to support efficient indexing in object recognition tasks.
该研究介绍了一种新的轴向表示的二维和三维形状,实现宾福德的 带状物和一般圆柱体的原始概念。 不像 当前基于广义圆柱体的表示方案,其使用更多限制性参数模型,例如直齐次广义圆柱体,并且因此限于这些模型的实例,可以构造这种表示 通过计算来计算任意物体 的 由对象和参数化平面的相交区域定义的多维高度场的一维谷。 本研究的主要目标是:(1)给出一个数据驱动的、可操作的带状物和广义圆柱体的定义,从而产生从二维或三维数据构造任意形状描述的实用算法; (二) 到 建立正式的 性能 的 代表,目的是评估其 范围 并开发用于检测图像中的广义圆柱投影的严格算法;以及(3)开发原则性方法, 部分 分解,并使用构建的部分-整体层次结构来支持对象识别任务中的高效索引。
