Linear algorithms are presented for computing the 3-D structure and motion of vehicles in traffic scenes under the ground-plane constraint. Point matches in multiple image frames are used. The algorithms first determine the inter-frame rotation angles, then the point depths, and finally the inter-frame translations. All computations are linear and require no parameter tuning. The algorithms are...

Interactive tridimensional visualization of terrain models can be found in Geographical Information Systems and computer games. Both applications share the need for high performance algorithms that are tailored to produce textured images in interactive time, say at least 5 frames per second. In this paper we propose and analyze the extension of a well known ray casting algorithm to the case whe...

abstract. certain facts about frames and generalized frames (g- frames) are extended for the g-frames for hilbert c*-modules. it is shown that g-frames for hilbert c*-modules share several useful properties with those for hilbert spaces. the paper also character- izes the operators which preserve the class of g-frames for hilbert c*-modules. moreover, a necessary and suffcient condition is ob- ...

We propose a real-time capturing and 3D visualization method based on integral imaging. We applied real-time conversion algorithm to conventional integral imaging pickup system. Gap control method with depth plane adjustment is also applied to improve image quality. Implemented system provides real-time 3D images with ultra high definition resolution in 20 frames per second, and the observer ca...

This paper presents an interactive video visualization technique called video cubism. With this technique, video data is considered to be a block of three dimensional data where frames of video data comprise the third dimension. The user can observe and manipulate a cut plane or cut sphere through the video data. An external real-time video source may also be attached to the video cube. The vis...

We present a new CMOS readout architecture that provides near lossless in-stream compression of 10-bit video data at rates up to 1000 frames per second on large focal plane arrays. The correctness of the circuit design in performing all logic operations at data rates of interest has been fully tested and verified in fabricated prototype arrays. The architecture can be combined with different se...

We consider the problem of estimating the motion of a light source, given a sequence of images of a stationary, unknown object illuminated by it. The apparent ow eld induced on the image plane is used to recover the motion parameters. The motion is assumed to be uniform between the successive image frames. A recursive total least squares estimator is developed in this paper to track the motion ...

A definition of progressive collapse is offered and two examples of the phenomenon described. Attention is drawn to potential sources of abnormal loads that should be examined when designing for progressive collapse performance. A plane frame computer program is described for the collapse analysis of reinforced concrete frames using finite elements and a quasi-static approach. The paper conclud...

Abstract We examine the rotation of the plane of polarization for linearly polarized light rays by the weak gravitational field of an isolated physical system. Based on the rotation of inertial frames, we review the general integral expression for the net rotation. We apply this formula, analogue to the usual electromagnetic Faraday effect, to some interesting astrophysical systems: uniformly s...
