Active perception (active vision specifically) is defined as a study of modeling and control
strategies for perception. Local methods are distinguished from global models by their extent …

This paper addresses the problem of parametric representation and estimation of complex
planar curves in 2-D, surfaces in 3-D and nonplanar space curves in 3-D. Curves and …

Dynamic programming is discussed as an approach to solving variational problems in
vision. Dynamic programming ensures global optimality of the solution, is numerically stable …

A representation of objects by their parts is the dominant strategy for representing complex
3D objects in many disciplines. In computer vision and robotics, superquadrics are among …

A survey is presented of some of the surface reconstruction methods that can be found in the
literature; the focus is on a small, recent, and important subset of the published …

We present an approach to the recovery of 3-D volumetric primitives from a single 2-D
image. The approach first takes a set of 3-D volumetric modeling primitives and generates a …

Interest in algebraic curves and surfaces of high degree as geometric models or shape
descriptors for different model-based computer vision tasks has increased in recent years …

Absfmct-Acquisition of 3-D scene information has focused on either passive 2-D imaging
methods (stereopsis, structure from motion, etc.) or 3-D range sensing methods (structured …

We present an approach to the recovery and recognition of 3-D objects from a single 2-D
image. The approach is motivated by the need for more powerful indexing primitives, and …

We present an approach to function-based object recognition that reasons about the
functionality of an object's intuitive parts. We extend the popular" recognition by parts" shape …
