Today's network control and management traffic are limited by their reliance on existing data networks. Fate sharing in this context is highly undesirable, since control traffic has very different availability and traffic delivery requirements. In this paper, we explore the feasibility of building a dedicated wireless <i>facilities network</i> for data(More)
In this paper we present a novel approach to estimate and analyze 3D uid structur eand motion of clouds from multi-spectrum 2D cloud image sequences. A c curate cloud-top structure and motion are very important for a host of meteorolo gic al and climate applications. However, due to the extremely complex nature of cloud uid motion, classical nonrigid motion(More)
Image sequences capturing Hurricane Luis through meteorological satellites (GOES-8 and GOES-9) are used to estimate hurricane-top heights (structure) and hurricane winds (motion). This problem is diicult not only due to the absence of correspondences but also due to the lack of depth cues in the 2D hurricane images (scaled orthographic projection). In this(More)
Superquadrics are a family of parametric shapes which can model a diverse set of objects. They have received significant attention because of their compact representation and robust methods for recovery of 3D models. However, their assumption of intrinsical symmetry fails in modeling numerous real-world examples such as the human body, animals, and other(More)
Fueled by the widespread adoption of sensor-enabled smartphones, mobile crowdsourcing is an area of rapid innovation. Many crowd-powered sensor systems are now part of our daily life -- for example, providing highway congestion information. However, participation in these systems can easily expose users to a significant drain on already limited mobile(More)
ÐTracking both structure and motion of nonrigid objects from monocular images is an important problem in vision. In this paper, a hierarchical method which integrates local analysis (that recovers small details) and global analysis (that appropriately limits possible nonrigid behaviors) is developed to recover dense depth values and nonrigid motion from a(More)
