Tradeoffs exist between the baseline or distance between cameras and the difficulty of matching corresponding points in stereo and structure from motion. Smaller baselines result in reduced disparities reducing the accuracy of depth estimation. Larger baselines increase the range of observed disparities, but also increase the difficulty of finding corresponding points. In this paper, we explore...

Wide baseline matching of images is an important problem in multimedia and computer vision. Recently a class of spectral methods have been proposed for tasks like segmentation. In this paper we propose a spectral algorithm for wide baseline matching.

This year AT&T participated in the ad-hoc task and the Filtering, SDR, and VLC tracks. Most of our eeort for TREC-7 was concentrated on SDR and VLC tracks. On the ltering track, we tested a preliminary version of a text classiication toolkit that we have been developing over the last year. In the ad-hoc task, we introduce a new tf-factor in our term weighting scheme and use a simpliied retrieva...

We present the design of a self-routing quantum packet switch which improves on a previous design given by the authors [1]. Like the earlier design, this switch too routes packets represented by quantum bits (qubits) but it reduces the routing overhead per packet from O(logN) qubits to O(1) qubits by eliminating the need for an extra “dummy” inputoutput pair and their associated “dummy” packets...

This paper presents a stereo matching method which uses multiple stereo pairs with various baselines to obtain precise depth estimates without suffering from ambiguity. In stereo processing, a short baseline means that the estimated depth will be less precise due to narrow triangulation. For more precise depth estimation, a longer baseline is desired. With a longer baseline, however, a larger d...
