Towards Emotion Recognition: A Persistent Entropy Application
, 2018 Emotion recognition and classification is a very active area of research. In this paper, we present a first approach to emotion classification using persistent entropy and support vector machines. A topology-based model is applied to obtain a single real

Sinusoidal modeling using psychoacoustic-adaptive matching pursuits
IEEE Signal Processing Letters, 2002 We propose a segment-based matching-pursuit algorithm where the psychoacoustical properties of the human auditory system are taken into account. Rather than scaling the dictionary elements according to auditory perception, we define a psychoacoustic-adaptive norm on the signal space that can be used for assigning the dictionary elements to the ...

Perceptibility of pitch changes in a tonal signal emitted by a moving source
Archives of Acoustics, 2016 The starting point for the experimental research described here was a psychoacoustic analysis of the Doppler effect. The investigations were performed under laboratory conditions using an electronic model of a moving source.

Investigating bottom-up auditory attention
Frontiers in Human Neuroscience, 2014 Bottom-up attention is a sensory-driven selection mechanism that directs perception towards a subset of the stimulus that is considered salient, or attention-grabbing. Most studies of bottom-up auditory attention have adapted frameworks similar to visual

Universal Adversarial Perturbations for Speech Recognition Systems [PDF]
, 2019 In this work, we demonstrate the existence of universal adversarial audio perturbations that cause mis-transcription of audio signals by automatic speech recognition (ASR) systems. We propose an algorithm to find a single quasi-imperceptible perturbation,

A Laboratory Method for Assessing Audibility and Localization of Rotorcraft Fly-In Noise [PDF]
The low frequency content of rotorcraft noise allows it to be heard over great distances. This factor contributes to the disruption of natural quiet in national parks and wilderness areas, and can lead to annoyance in populated areas.

MPEG-1 bitstreams processing for audio content analysis [PDF]
, 2002 In this paper, we present the MPEG-1 Audio bitstreams processing work which our research group is involved in. This work is primarily based on the processing of the encoded bitstream, and the extraction of useful audio features for the purposes of ...

A Review of Classical Lossless Data Compression Algorithmsand Their Contemporary Relevance [PDF]
Biuletyn Wojskowej Akademii TechnicznejCompression is data processing aimed at reducing the amount of information (e.g., for archiving and transfer). There is lossyand lossless compression. Compression algorithms can be either general-purpose or designed for specific types of data (e.g., for ...
