Evaluation of handwriting kinematics and pressure for differential diagnosis of Parkinson's disease
Peter Drotár, Jiří Mekyska, Irena Rektorová +3
Objective: We present the PaHaW Parkinson's disease handwriting database, consisting of handwriting samples from Parkinson's disease (PD) patients and healthy controls. Our goal is…
A comparative study between linear and nonlinear speech prediction
Marcos Faundez-Zanuy, Enric Monte, Francesc Vallverdú
This paper is focused on nonlinear prediction coding, which consists on the prediction of a speech sample based on a nonlinear combination of previous samples. It is known that in…
A Naturalistic Database of Thermal Emotional Facial Expressions and Effects of Induced Emotions on Memory
Anna Esposito, Vincenzo Capuano, Jiri Mekyska +1
This work defines a procedure for collecting naturally induced emotional facial expressions through the vision of movie excerpts with high emotional contents and reports experiment…
Fast on-line signature recognition based on VQ with time modeling
Juan-Manuel Pascual-Gaspar, Marcos Faundez-Zanuy, Carlos Vivaracho
This paper proposes a multi-section vector quantization approach for on-line signature recognition. We have used the MCYT database, which consists of 330 users and 25 skilled forge…
Analysis of Disfluencies for automatic detection of Mild Cognitive Impartment: a deep learning approach
Karmele Lopez-de-Ipiña, Unai Martinez de Lizarduy, Pilar Calvo +5
The so-called Mild Cognitive Impairment (MCI) or cognitive loss appears in a previous stage before Alzheimer's Disease (AD), but it does not seem sufficiently severe to interfere i…
Perceptual Features as Markers of Parkinson's Disease: The Issue of Clinical Interpretability
Jiri Mekyska, Zdenek Smekal, Zoltan Galaz +4
Up to 90% of patients with Parkinson's disease (PD) suffer from hypokinetic dysathria (HD) which is also manifested in the field of phonation. Clinical signs of HD like monoloudnes…
Contribution of Different Handwriting Modalities to Differential Diagnosis of Parkinson's Disease
Peter Drotár, Jiří Mekyska, Zdeněk Smékal +3
In this paper, we evaluate the contribution of different handwriting modalities to the diagnosis of Parkinson's disease. We analyse on-surface movement, in-air movement and pressur…
Selection of entropy based features for the analysis of the Archimedes' spiral applied to essential tremor
Karmele López-De-Ipiña, Alberto Bergareche, Patricia De La Riva +10
Biomedical systems are regulated by interacting mechanisms that operate across multiple spatial and temporal scales and produce biosignals with linear and non-linear information in…
Automatic analysis of Categorical Verbal Fluency for Mild Cognitive Impartment detection: a non-linear language independent approach
Karmele López-De-Ipiña, Unai Martinez de Lizarduy, Nora Barroso +4
Alzheimer's disease (AD) is one the main causes of dementia in the world and the patients develop severe disability and sometime full dependence. In previous stages Mild Cognitive…
Gender classification by means of online uppercase handwriting: A text-dependent allographic approach
Enric Sesa-Nogueras, Marcos Faundez-Zanuy, Josep Roure-Alcobé
This paper presents a gender classification schema based on online handwriting. Using samples acquired with a digital tablet that captures the dynamics of the writing, it classifie…
Robust and Complex Approach of Pathological Speech Signal Analysis
Jiri Mekyska, Eva Janousova, Pedro Gomez-Vilda +8
This paper presents a study of the approaches in the state-of-the-art in the field of pathological speech signal analysis with a special focus on parametrization techniques. It pro…
Assessing Progress of Parkinson s Disease Using Acoustic Analysis of Phonation
Jiri Mekyska, Zoltan Galaz, Zdenek Mzourek +9
This paper deals with a complex acoustic analysis of phonation in patients with Parkinson's disease (PD) with a special focus on estimation of disease progress that is described by…
Multi-focus thermal image fusion
Radek Benes, Pavel Dvorak, Marcos Faundez-Zanuy +2
This paper proposes a novel algorithm for multi-focus thermal image fusion. The algorithm is based on local activity analysis and advanced pre-selection of images into fusion proce…
On the focusing of thermal images
Marcos Faundez-Zanuy, Jiří Mekyska, Virginia Espinosa-Duro
In this paper we present a new thermographic image database suitable for the analysis of automatic focus measures. This database consists of 8 different sets of scenes, where each…
A multimodal approach for Parkinson disease analysis
Marcos Faundez-Zanuy, Antonio Satue-Villar, Jiri Mekyska +9
Parkinson's disease (PD) is the second most frequent neurodegenerative disease with prevalence among general population reaching 0.1-1 %, and an annual incidence between 1.3-2.0/10…
A new face database simultaneously acquired in visible, near infrared and thermal spectrum
Virginia Espinosa-Duró, Marcos Faundez-Zanuy, Jiří Mekyska
In this paper we present a new database acquired with three different sensors (visible, near infrared and thermal) under different illumination conditions. This database consists o…
State-of-the-art in speaker recognition
Marcos Faundez-Zanuy, Enric Monte-Moreno
Recent advances in speech technologies have produced new tools that can be used to improve the performance and flexibility of speaker recognition While there are few degrees of fre…
On-line signature verification system with failure to enroll managing
Joan Fabregas, Marcos Faundez-Zanuy
In this paper we simulate a real biometric verification system based on on-line signatures. For this purpose we have split the MCYT signature database in three subsets: one for cla…
Biometric security technology
Marcos Faundez-Zanuy
This paper presents an overview of the main topics related to biometric security technology, with the main purpose to provide a primer on this subject. Biometrics can offer greater…
