Category-Blind Human Action Recognition: A Practical Recognition System [PDF]
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
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 ...

Variational semi-blind sparse deconvolution with orthogonal kernel bases and its application to MRFM [PDF]
We present a variational Bayesian method of joint image reconstruction and point spread function (PSF) estimation when the PSF of the imaging device is only partially known.

Speech enhancement via combination of Wiener filter and blind source separation [PDF]
Automatic speech recognition (ASR) often fails in acoustically noisy environments. Aimed to improve speech recognition scores of an ASR in a real-life like acoustical environment, a speech pre-processing system is proposed in this paper, which consists ...

An Improved Blind Recognition Method of the Convolutional Interleaver Parameters in a Noisy Channel
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,

Reliable Ultrasonic Obstacle Recognition for Outdoor Blind Navigation
A reliable state-of-the-art obstacle detection algorithm is proposed for a mobile application that will analyze in real time the data received by an external sonar device and decide the need to audibly warn the blind person about near field obstacles ...

Braille Recognition for Reducing Asymmetric Communication between the Blind and Non-Blind [PDF]
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.
