We propose a new system for vision-based mobile robot navigation in an unmodeled environment. Simple, unobtrusive artificial landmarks are used as and localization aids. The landmark patterns designed so that they can be reliably detected real-time images taken with the robot's camera over wide range of viewing configurations. code recognition algorithm is available web site.
We present a new method for the robust detection and matching of multiple planes in pairs images. Such can serve as stable landmarks vision-based urban navigation. Our approach starts from SIFT matches generates local homography hypotheses using recent J-linkage technique by Toldo Fusiello, randomized multi-model estimation algorithm. These are then globally merged, spatially analyzed, robustly fitted, checked stability. When tested on more than 30,000 image taken panoramic views college...
Uncertainty in the execution of robot motion plans must be accounted for geometric computations from which are obtained, especially case where position sensing is inaccurate. We give an Ο(n2 log n) algorithm to find a single commanded direction will guarantee successful plane specified start goal whenever such one-step possible. The account uncertainty and control, anticipate that may stick on or slide along obstacle surfaces with it comes contact. This bound improves best previous by...
Introduction: Computed tomography scans of the head (CTH) are an important component initial patient evaluation after blunt trauma in select patients. Here we review findings CTH performed for mild traumatic brain injury (TBI) at a Level I center over two-year period. We subsequently discuss role and limitations published clinical decision rules aiming to decrease unnecessary TBI Methods: reviewed all Emergency Department obtained between 2010 2011. Patient demographics radiology report...
In this paper we address the problem of planning reliable landmarkbased robot navigation strategies in presence significant sensor uncertainty. The environments are modeled with directed weighted graphs which edges can be traversed given probabilities. To construct robust and efficient plans, compute “expected shortest paths” such graphs. We formulate expected paths as a Markov decision process provide two algorithms for its solution. demonstrate practicality our approach using an extensive...

This paper presents a new method for navigation and localization of mobile robot equipped with an omnidirectional camera. We represent the environment using collection one-dimensional panoramic images formed by averaging center scanlines cylindrical view. Such 1D can be stored processed few resources, allowing fairly dense sampling environment. Image matching proceeds in real time dynamic programming on scale-invariant features extracted from each circular By analyzing shape curve, relative...
An offset-polygon annulus region is defined in terms of a polygon P and distance δ > 0 (offset P). In this paper we solve several containment problems for regions with respect to an input point set. Optimization criteria include both maximizing the number points contained fixed size minimizing needed contain all points. We address following variants problem: placement convex as well simple polygon; by translation only, or rotation; off-line on-line versions corresponding decision problems;...

In this special session, we share a variety of ways in which CS 1 courses can broaden their focus beyond programming. These strive to effectively introduce the fundamental ideas computer science, and importance computing broader contexts, without sacrificing programming rigor.
We discuss our recent experience offering a single introductory computer science course for all students with no prior coursework. The new interleaves material from traditional CS0 and CS1 courses, providing both broad overview an appreciation the algorithmic foundations of discipline science. describe motivation this approach, content course, some conclusions based on experiences feedback student evaluations.

We consider the problem of planning configuration a sensor within context robotic task. In this paper, we focus on geometrically specified tasks in plane, and give algorithms for computing regions from which an idealized point-and-shoot can detect polygonal robot. Our main algorithm allows configurations robot may be partially obstructed, computes detected as it translates through goal at known orientation. This runs time O(kmn/sup 3/(n+m)) environment complexity n, m, k. The constructed...
The Computer Science Principles project is a collaborative effort sponsored by the NSF and led group of faculty working together with College Board. Our goal to design teach new introductory course in computer science that will attract broader range students science. This would serve as Advanced Placement (AP) addition current CS AP A.
