IRR: A Blind Guide

A Guide Dog for the Blind

A Mobile-Cloud Pedestrian Crossing Guide for the Blind

The ability to detect the status of pedestrian signals at street intersections is a critical aspect of safe outdoor navigation for the blind and visually-impaired, especially in unfamiliar environments. Existing outdoor navigation devices for the blind prove insufficient in providing such guidance due to their reliance on limited mobile computational resources. In this work, we propose a mobile...

Blobby: How to Guide a Blind Person Indoors

For the majority of blind people, walking in unknown places is a very difficult, or even impossible, task to perform, when without help. The adoption of the white cane is the main aid to a blind user’s mobility. However, the major difficulties arise in the orientation task. The lack of reference points and the inability to access visual cues are its main causes. We aim to overcome this issue al...

Blind Deconvolution Problems: A Literature Review and Practitioner’s Guide

Blind deconvolution is the process of deconvolving a known acquired signal with an unknown point spread function (PSF) or channel encoding, by jointly estimating the system’s input as well as the system’s PSF. Models for this problem often present as the convolution or product of the underlying signal and the system’s PSF. The acquired signal is bi-linear in these two unknown signals (i.e. line...

On ultraproducts of Boolean algebras and irr

Anotated Content §1 Consistent inequality [We prove the consistency of irr(i<κ B i /D) < i<κ irr(B i)/D where D is an ultrafilter on κ and each B i is a Boolean Algebra. This solves the last problem of this form from the Monk's list of problems in [M2], that is number 35. The solution applies to many other properties, e.g. Souslinity.] §2 Consistency for small cardinals [We get similar results ...
