We present a system for interactively browsing and exploring large unstructured collections of photographs of a scene using a novel 3D interface. Our system consists of an image-based modeling front end that automatically computes the viewpoint of each photograph as well as a sparse 3D model

matching task. The cue combination approach, which successfully accounts for our data, relies on quite different principles from those underlying traditional models of 3D reconstruction.

, and that the ambitious pre-launch specifications set by users for Reference3D (16 metres for 90 % of points) can be met using data from the HRS instrument on SPOT 5, provided the many parameters involved are monitored continuously. Such monitoring is essential if we are to dispense with ground control points (GCPs

in that it cannot be written as the negative gradient of a potential function, and the corresponding snake is formulated directly from a force balance condition rather than a variational formulation. Using several two-dimensional (2-D) examples and one three-dimensional (3-D) example, we show that GVF has a large

the electroencephalogram (EEG) during MRI experiments, small tubular salt bridges (0.8 mm i.d.) were implanted in small holes through the skull that were located inside the area encircled by the surface coil used for NMR signal detection. Care was taken not to break the dura. Magnetic Resonance Microimaging. Gradient

large-scale VEs. The aid exploits 3D arrows to point towards the objects and places the user is interested in. We illustrate and discuss the experimental evaluation we carried out to assess the usefulness of the proposed solution, contrasting it with more traditional 2D navigation aids. In particular

We consider four important aspects of LBS namely standards, positioning, visualisation and geo-DBMS, which we

This paper presents a prototype system for Blind Source Separation (BSS) of many speech signals and describes the techniques used in the system. Our system uses 8 microphones located at the vertexes of a 4cm×4cm×4cm cube and has the ability to separate signals distributed in threedimensional space

Abstract. This paper presents a novel approach to the problem of es-timating and tracking 3D locations of multiple targets in a scene using measurements gathered from multiple calibrated cameras. Estimation and tracking is jointly achieved by a newly conceived computational process, the Projective

The paper proposes a simple method to determine the 3-D location and shape parameters of a right circular cone using structured lights. A vital concept in the proposed method is to convert the complex curved stripe pattern into an equivalent, but simpler, linear stripe pattern. The conic surface
