We recently demonstrated a new approach to mul-tiframe structure from motion from point features which, in the appropriate domain, provably reconstructs structure and motion correctly. The algorithm works for general motion and large perspective eeects. In this paper, we describe how to adapt our approach to translational motion lying along a line or in a plane, with arbitrary rotations. An ana...

We present a technique to fuse inertial and visual information for real-time navigation applications. The combined model exhibits bounded bias, autocalibrates the camera-to-IMU transformation (eliminating the need for precise measurement or construction), and updates an estimate of the gravity vector. We analyze of the observability of the combined system, and discuss the implementation of a fi...

It is largely unknown why certain infected hosts shed Herpes Simplex Virus-2 (HSV-2) more frequently and have more severe disease manifestations than others. One idea is that different density or functional capacity of tissue resident effector memory CD8+ T-cells between infected persons may explain phenotypic variability. To generate hypotheses for contrasting shedding patterns in different in...

Validation is a familiar topic in computing, generally as a mechanism to protect a database from the effects of inappropriate data with the side effect of detecting some errors. As such, the validation rules are determined from the database schema using well understood methodologies. This paper takes a different view by examining digital validation as one of a set of processes that are designed...

In this paper, we tackle the problem of estimating the depth of a scene from a monocular video sequence. In particular, we handle challenging scenarios, such as non-translational camera motion and dynamic scenes, where traditional structure from motion and motion stereo methods do not apply. To this end, we first study the problem of depth estimation from a single image. In this context, we exp...

Inversion of Scholte wave is one of the most common methods to estimate the shear speeds in the bottom. This inversion involves running a forward model, with shear speeds in the sediment among the input parameters, and minimizing the data-model mismatch. A numerical model is developed based on the dynamic stiffness matrix approach to model the phase velocity dispersion of Scholte waves in this ...

In a climate change context, volume variations of glaciers can be efficiently evaluated by comparison of Digital Elevation Models (DEM) of the ice surface, taken at different time frames. However, traditional methods of DEM reconstruction lack either in resolution or they are costly, considering the remoteness of certain basins. This study aims for testing a method called Structure from Motion ...

We provide a comprehensive comparison of a coupled channel calculation, the asymptotic bound-state model (ABM), and the multichannel quantum defect theory (MQDT). Quantitative results for 6Li -133Cs are presented and compared to previously measured 6Li -133Cs Feshbach resonances (FRs) [Repp et al., Phys. Rev. A 87, 010701(R) (2013)]. We demonstrate how the accuracy of the ABM can be stepwise im...
