Mobile objects are frequently confined to move on a ground surface which, locally at least, is approximately flat. Existing structure-from-motion (SFM) algorithms make no use of real-world motion constraints of this kind. In this paper we present a simple novel SFM algorithm whereby the above motion constraints can be conveniently incorporated into the constraint equations on the relative depth...

We use Stochastic Fluid Models (SFM) for control and optimization (rather than performance analysis) of communication networks, focusing on problems of admission control. We consider a SFM with an uncontrolled traffic class and a controlled traffic class subject to threshold-based admission control. We derive gradient estimators for packet loss and workload related performance metrics with resp...

Results: The rise in serum calcium observed after ingestion of calcium carbonate with a calcium peak of 0.56 mg/dl (p=0.032), and it was higher when compared to SFM 0.26 mg/dl (p=0.284). There was no significant elevation of serum calcium after ingestion of SFM. The calcium responses were negative after the administration of omeprazole in comparison with the use of calcium carbonate and SFM, re...

The vertical dimensions of the well-characterized test samples tobacco mosaic virus, T4 bacteriophage polyhead, purple membrane, and hexagonally packed intermediate (HPI) layer were investigated by tapping mode scanning force microscopy (SFM) in solution. Purple membrane and HPI layer were imaged in both contact mode and tapping mode SFM for direct comparison. All vertical dimensions match the ...

This study aimed to evaluate whole white lupin (cv. Amiga) seeds as an alternative dietary crude protein source to soybean and sunflower meal. Diets contained soybean meal (10%, SBM diet), sunflower meal (17%, SFM diet) or white lupin seeds (15%, WL diet) as the main protein source. The experimental diets were similar in the level of crude protein (16.2%), starch (15.0%), fat (4.6%) and in the ...

Abstract— The estimation of a 3D shape of a scene as well as the position and the orientation of the sensor has been extensively researched, especially for Virtual Reality (VR) and Robotics systems. To achieve this estimation, a system that consists of a laser range sensor, Global Positioning System (GPS), and Gyro sensor has been proposed, actually constructed, and used. However, it is usually...

This paper describes a method to construct a stationary environmental map and estimate the ego-motion of a mobile robot from unknown planar motion by using an omni-directional vision sensor. Most environments where mobile robot works are limited to two-dimensional space and the environmental map which is necessary for mobile robot navigation has also two dimensions. However, conventional “Struc...

Structure from motion (SFM) is the problem of reconstructing the geometry of a scene from a stream of images on which features have been tracked. In this paper, we consider a projective camera model and assume that the internal parameters of the camera are known. Our goal is to reconstruct the geometry of the scene up to a rigid motion (i.e. Euclidean reconstruction.) It has been shown that est...

Imaging systems consisting of multiple conventional cameras are of increasing interest for computer vision applications such as Structure from Motion (SfM) due to their large combined field of view and high composite image resolution. In this work we present a SfM framework for multi-camera systems w/o overlapping camera views that integrates on-line extrinsic camera calibration, local scene re...
