In this Master thesis project, we tackle the problem of 3D indoor scene understanding from a single image. Following existing approaches, we parameterize the problem as one of estimating the faces of a 3D cuboid. Towards this goal, we propose a generative model of the scene, which takes advantage of sophisticated image features while utilizing a simple prior learned from the statistics of room ...

This paper is concerned with the development o f an expert system which determines the best grasp configuration t o pick up a rectangular box. This two level system first chooses from a predetermined set of grasps, the ones best suited for the task using a set of rules. and then computes a quality index for each possible configuration. The program is written in LISP and was tested for many diff...

Engineering industry requires line drawings for manufacturing, machining and production of engineering equipments/objects. The generation of these paper-based drawings or computerized drawings is a complex and time consuming task. Conventionally, these drawings contain three two dimensional (2D) orthographic views, namely top, front and side of an object. Modern trends in engineering industry r...

Reconstruction from a single view of architectural scenes is possible thanks to the automatic identification of structural perspective elements in the view. Reliable and accurate reconstruction depends strongly on a robust estimation of vanishing points. In this paper we compare different approaches for estimation of vanishing points, and we justify our choice of Danish estimator. The intersect...

This paper presents the integration of an Octree modeller, an assembly planning system, and a robotic cell to build approximate prototypes directly from 3D model data. The integration demonstrates the feasibility of an assembly based rapid prototyping approach referred to as OcBlox, which approximates Octree representations of 3D models with “Blox”. These cuboid units are automatically assemble...

BACKGROUND Surgical treatment and clinical management of foot pathology requires accurate, reliable assessment of foot deformities. Foot and ankle deformities are multi-planar and therefore difficult to quantify by standard radiographs. Three-dimensional (3D) imaging modalities have been used to define bone orientations using inertial axes based on bone shape, but these inertial axes can fail t...
