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,

Braille Recognition for Reducing Asymmetric Communication between the Blind and Non-Blind [PDF]
Symmetry, 2020 Assistive braille technology has existed for many years with the purpose of aiding the blind in performing common tasks such as reading, writing, and communicating with others. Such technologies are aimed towards helping those who are visually impaired to better adapt to the visual world.

Fast Blind Recognition of Channel Codes
IEEE Transactions on Communications, 2014 We present a fast algorithm that, for a given input sequence and a linear channel code, computes the syndrome posterior probability (SPP) of the code, i.e., the probability that all parity check relations of the code are satisfied. According to this algorithm, the SPP can be computed blindly, i.e., given the soft information on a received sequence we ...

Robust and Effective Component-Based Banknote Recognition for the Blind [PDF]
IEEE Transactions on Systems, Man, and Cybernetics, Part C (Applications and Reviews), 2012 We develop a novel camera-based computer vision technology to automatically recognize banknotes for assisting visually impaired people. Our banknote recognition system is robust and effective with the following features: 1) high accuracy: high true recognition rate and low false recognition rate, 2) robustness: handles a variety of currency designs and
