Model Construction from a Single Perspective View using Shape from Symmetry
نویسندگان
چکیده
A new method is described Struct we from Symmetry (SFS) in which objects possessing bilateral symmetry may be reconstructed from a single perspective view. The algorithm exploits the groundplane constraint [9, 14] and assumes a camera model, to allow 3D recovery up to scale. The SFS algorithm has been implemented in the form of an interactive tool. The user marks a set of symmetric object points in an image, and a complete facet model description is generated as output. The tool has been extensively used to create models for the vision system developed in the VIEWS project. The algorithm has potential for automatic structure recovery if methods for identifying symmetry points can be improved.

On the Multi-View Fitting and Construction of Dense Deformable Face Models
Active Appearance Models (AAMs) are generative, parametric models that have been successfully used in the past to model deformable objects such as human faces. Fitting an AAM to an image consists of minimizing the error between the input image and the closest model instance; i.e. solving a nonlinear optimization problem. In this thesis we study three important topics related to deformable face ...
متن کاملRecognising rotationally symmetric surfaces from their outlines
Recognising a curved surface from its outline in a single view is a major open problem in computer vision. This paper shows techniques for recognising a signiicant class of surfaces from a single perspective view. The approach uses geometrical facts about bitangencies, creases, and innections to compute descriptions of the surface's shape from its image outline. These descriptions are unaaected...
متن کاملReconstructing Three-dimensional Specific Curve Building Models from a Single Perspective View Image
This paper presents a systematic approach to reconstruct 3D models of complex buildings with specific curve structures from single perspective view images. The proposed method begins with the automatic extraction of straight feature lines and corner points. Three mutually orthogonal vanishing points are then calculated automatically and robustly for reconstructing three-dimensional regular (pla...
متن کاملFolded Sheet Versus Transparent Sheet Models for Human Symmetry Judgments
As a contribution to the mysteries of human symmetry perception, reaction time data were collected on the detection of symmetry or repetition violations, in the context of short term visual memory studies. The histograms for reaction time distributions are rather narrow in the case of symmetry judgments. Their analysis was performed in terms of a simple kinetic model of a mental process in two ...
