d model extraction from uncalibrated 2-d camera views. [7] Brian Curless and Marc Levoy. A volumetric method for building complex models from range images.

in recent years, routing has been the most focused area in ad hoc networks research. on-demand routing in particular, is widely developed in bandwidth constrained mobile wireless ad hoc networks because of its effectiveness and efficiency. most proposed on-demand routing protocols are built and relied on single route for each data session. whenever there is a link disconnection on the active ro...

-A highly effective predictive/preview display technique for telerobotic servicing in space under several seconds communication time delay has been demonstrated on a large laboratory scale in May 1993, involving the Jet Propulsion Laboratory as the simulated ground control station and, 2500 miles away, the Goddard Space Flight Center as the simulated satellite servicing set-up. The technique is...

In this paper, we address the problem of controlling a mobile stereo camera under image quantization noise. Assuming that a pair of images of a set of targets is available, the camera moves through a sequence of Next-Best-Views (NBVs), i.e., a sequence of views that minimize the trace of the targets’ cumulative state covariance, constructed using a realistic model of the stereo rig that capture...

In this paper a novel method for indexing views of 3D objects is presented. The topological properties of the regions of views of an object or of a set of objects are used to define an index based on region connection calculus and oriented matroid theory. Both are formalisms for qualitative spatial representation and reasoning and are complementary in the sense that, whereas region connection c...

Reconstruction from images has become a popular and inexpensive method of building 3D scenes. For this method to work, one has to determine the position and orientation of the camera at which the images where taken. Although the camera orientation can be done fully automatically, the results are sometimes inaccurate and incomplete. These problems can be solved by manual interactions. We present...

We present an image-space camera manipulation widget that supports visualization of the relationship of the camera with respect to the scene. The form of the widget presents the user with natural affordances for camera manipulation. Visual aids such as ghosting of the scene and preview animations are used to acquaint novice users with the functions of different parts of the widget. Mouse gestur...

This paper deals with the ego-motion estimation (motion of the camera) from two views. When we want to estimate the ego-motion we have to nd correspondences and we need a calibrated camera. In this paper we solve the problem how to propagate known camera calibration errors into the uncertainty of the motion parameters. We present a linear estimate of the uncertainty of the motion parameters bas...

A new technique is proposed for calibrating a 3D modeling system with variable zoom based on multi-view stereo image analysis. The 3D modeling system uses a stereo camera with variable zoom setting and a turntable for rotating an object. Given an object whose complete 3D model (mesh and texture-map) needs to be generated, the object is placed on the turntable and stereo images of the object are...

We present a novel approach for establishing multiple-view feature correspondences along an unordered set of images taken from substantially different viewpoints. While recently several wide-baseline stereo (WBS) algorithms have appeared, the N-view case is largely unexplored. In this paper, an established WBS algorithm is used to extract and match features in pairs of views. The pairwise match...
