Computer vision techniques have been applied for rapid
and accurate structure recovery in many fields. Most methods
perform poorly in areas containing little or no texture
and in presence of repetitive patterns. We present a
portable, cost-effective pattern projector system powered
by the flash of a camera, to aid the reconstruction of such
areas....

We present an image-based Simultaneous Localization and Mapping (SLAM) framework with online, appearanceonly loop closing. We adopt a layered approach with metric maps over small areas at the local level and a global, graph-based abstract topological framework to build consistent maps over large distances....

Detection and tracking of moving vehicles in airborne videos is a challenging problem. Many approaches have been proposed to improve motion segmentation on frameby-frame and pixel-by-pixel bases, however, little attention has been paid to analyze the long-term motion pattern, which is a distinctive property for moving vehicles in airborne videos....

The aim of this paper is to address the problem of recognizing human group activities in surveillance videos. This task has great potentials in practice, however was rarely studied due to the lack of benchmark database and the difficulties caused by large intra-class variations. Our contributions are two-fold....

Consider a projector-camera setup where a sinusoidal pattern is projected onto the scene, and an image of the objects imprinted with the pattern is captured by the camera. In this configuration, the local frequency of the sinusoidal pattern as seen by the camera is a function of both the frequency of the projected sinusoid and the local geometry of objects in the scene....

Surface reconstruction from gradient fields is an important final step in several applications involving gradient manipulations and estimations. Typically, the resulting gradient field is nonintegrable due to linear/non-linear gradient manipulations, or due to presence of noise/outliers in gradient estimation. In this paper, we analyze integrability as error correction, inspired from ...
