Localizing Overlapping Parts by Searching the Interpretation Tree
TL;DR: The approach operates by examining all hypotheses about pairings between sensed data and object surfaces and efficiently discarding inconsistent ones by using local constraints on distances between faces, angles between face normals, and angles of vectors between sensed points.

Abstract: This paper discusses how local measurements of positions and surface normals may be used to identify and locate overlapping objects. The objects are modeled as polyhedra (or polygons) having up to six degrees of positional freedom relative to the sensors. The approach operates by examining all hypotheses about pairings between sensed data and object surfaces and efficiently discarding inconsistent ones by using local constraints on: distances between faces, angles between face normals, and angles (relative to the surface normals) of vectors between sensed points. The method described here is an extension of a method for recognition and localization of nonoverlapping parts previously described in [18] and [15].

Shape disassembly using generating merging probability
TL;DR: This paper proposes an new approach in decomposing compound shapes without prior knowledge of the scene by exploiting the fact that planar shapes can be completely described by contour segments, and can be decomposed at their maximum concavity into simpler objects.

TL;DR: This thesis will attempt to model the shapes of objects in a way that is robust to both deformations and occlusions, and develop a model that allows us to recover the hidden parts of occluded objects and which maintains information about the object boundary for use in robotic grasp planning.

Theory of Edge Detection
David Marr,Ellen C. Hildreth +1 more
TL;DR: The theory of edge detection explains several basic psychophysical findings, and the operation of forming oriented zero-crossing segments from the output of centre-surround ∇2G filters acting on the image forms the basis for a physiological model of simple cells.
