Implementation of an Obstacle Recognition System for the Blind [PDF]
Applied Sciences, 2019 The blind encounter commuting risks, such as failing to recognize and avoid obstacles while walking, but protective support systems are lacking. Acoustic signals at crosswalk lights are activated by button or remote control; however, these signals are ...

Language-familiarity effect on voice recognition by blind listeners [PDF]
JASA Express Letters, 2021 The current study compared the language-familiarity effect on voice recognition by blind listeners and sighted individuals. Both groups performed better on the recognition of native voices than nonnative voices, but the language-familiarity effect is ...

Blind recognition of binary cyclic codes [PDF]
EURASIP Journal on Wireless Communications and Networking, 2013 Abstract A solution to blind recognition of binary cyclic codes is proposed in this paper. This problem could be addressed on the context of non-cooperative communications or adaptive coding and modulations. We consider it as a reverse engineering problem of error-correcting coding.

Voice Recognition in Face-Blind Patients [PDF]
Cerebral Cortex, 2014 Right or bilateral anterior temporal damage can impair face recognition, but whether this is an associative variant of prosopagnosia or part of a multimodal disorder of person recognition is an unsettled question, with implications for cognitive and neuroanatomic models of person recognition.

Gesture Recognition System for the Blind
Perspectives in Communication, Embedded-Systems and Signal-Processing - PiCES, 2021 Several assistive technologies are booming up now-a-days to help the specially abled – it could be guiding walking sticks for the blind community, optical readers, wheelchairs and many more. However, very less research has been conducted on helping the blind access ATMs.

Category-Blind Human Action Recognition: A Practical Recognition System [PDF]
2015 IEEE International Conference on Computer Vision (ICCV), 2015 Existing human action recognition systems for 3D sequences obtained from the depth camera are designed to cope with only one action category, either single-person action or two-person interaction, and are difficult to be extended to scenarios where both action categories co-exist.

Blind Signal Dereverberation for Machine Speech Recognition
CoRR, 2022 We present a method to remove unknown convolutive noise introduced to speech by reverberations of recording environments, utilizing some amount of training speech data from the reverberant environment, and any available non-reverberant speech data. Using Fourier transform computed over long temporal windows, which ideally cover the entire room impulse ...

An Improved Blind Recognition Method of the Convolutional Interleaver Parameters in a Noisy Channel
IEEE Access, 2019 In a digital communication system, forward error correction (FEC) codes and interleavers are implemented to code the data so as to improve the error performance, which is hindered by random and burst errors. In the context of noncooperative communication,
