Urban intersections are the most dangerous parts of a blind person’s travel. Proper alignment is necessary to enter the crosswalk in the right direction and avoid the danger of straying outside the crosswalk. Computer vision is a natural tool for providing such alignment information. However, little work has been done on algorithms for finding crosswalks for the blind, and most of it focuses on...

Facilitating safe pedestrian road crossings is a major prerequisite for urban environments. In multiple cities around the world, 3D crosswalks have been painted, which provoke an optical illusion, of e.g., crosswalk floating above road, in car drivers who approach crosswalk. However, to date, no detailed study users’ safety related perceptions on has conducted. Hence, we investigated drivers’ a...

In this study, we performed a validation analysis of a crosswalk that converts Functional Independence Measure (FIM) scores to Minimum Data Set (MDS) scores and vice versa in order to achieve score compatibility. Data from 2,130 patients were obtained from the Department of Veteran Affairs' Austin Automation Center. The conversion algorithm was tested at the (1) individual patient level, (2) cl...

The potential for machine learning systems to amplify social inequities and unfairness is receiving increasing popular academic attention. Much recent work has focused on developing algorithmic tools assess mitigate such unfairness. However, there little enhancing fairness in graph algorithms. Here, we develop a simple, effective general method, CrossWalk, that enhances of various algorithms, i...

Urban intersections are the most dangerous parts of a blind or visually impaired person's travel. To address this problem, this paper describes the novel "Crosswatch" system, which uses computer vision to provide information about the location and orientation of crosswalks to a blind or visually impaired pedestrian holding a camera cell phone. A prototype of the system runs on an off-the-shelf ...

The paper proposes different solutions to integrate CERIF in the environmental dataset domain, based on the quality of semantic mapping as well as on the characteristics of the CERIF data model. A two-way crosswalk is described resulting in the identification of a core of corresponding metadata and a proposal of extensions of the CERIF model. Extensions of ISO concepts are also described to pro...

Neurology® Clinical Practice 2010;75(Suppl 1):S56–S59 Medicare and some other carriers no longer allow use of the Consult code families. The government made this change to address problems in use of the Consult codes. Other existing codes are to be used in their place. The crosswalk to the other codes is complicated. Prolonged Services codes should be added in some cases. Neurologists need to u...
