Classification of ALS patients based on acoustic analysis of sustained vowel phonations
Maxim Vashkevich, Yulia Rushkevich
Amyotrophic lateral sclerosis (ALS) is incurable neurological disorder with rapidly progressive course. Common early symptoms of ALS are difficulty in swallowing and speech. Howeve…
Bulbar ALS Detection Based on Analysis of Voice Perturbation and Vibrato
Maxim Vashkevich, Alexander Petrovsky, Yuliya Rushkevich
On average the lack of biological markers causes a one year diagnostic delay to detect amyotrophic lateral sclerosis (ALS). To improve the diagnostic process an automatic voice ass…
Derivation of fast DCT algorithms using algebraic technique based on Galois theory
Maxim Vashkevich, Alexander Petrovsky
The paper presents an algebraic technique for derivation of fast discrete cosine transform (DCT) algorithms. The technique is based on the algebraic signal processing theory (ASP).…
A low multiplicative complexity fast recursive DCT-2 algorithm
Maxim Vashkevich, Alexander Petrovsky
A fast Discrete Cosine Transform (DCT) algorithm is introduced that can be of particular interest in image processing. The main features of the algorithm are regularity of the grap…
Practical design of multi-channel oversampled warped cosine-modulated filter banks
Maxim Vashkevich, Wanggen Wan, Alexander Petrovsky
A practical approach to optimal design of multichannel oversampled warped cosine-modulated filter banks (CMFB) is proposed. Warped CMFB is obtained by allpass transformation of uni…
FPGA implementation of short critical path CORDIC-based approximation of the eight-point DCT
Maxim Vashkevich, Marek Parfieniuk, Alexander Petrovsky
This paper presents an efficient approach for multiplierless implementation for eight-point DCT approximation, which based on coordinate rotation digital computer (CORDIC) algorith…
