    • Emotional state recognition performance improvement on a handwriting and drawing task 

      Nolazco Flores, Juan Arturo; Faundez-Zanuy, Marcos; Velázquez-Flores, O. A.; Cordasco, Gennaro; Esposito, Anna (IEEE Access. 2021 Feb 23;(9):28496-28504, 2021-02-21)
      In this work we combine time, spectral and cepstral features of the signal captured in a tablet to characterize depression, anxiety, and stress emotional state recognition on the EMOTHAW database. EMOTHAW ...
    • Exploiting spectral and cepstral handwriting features on diagnosing Parkinson’s disease 

      Nolazco Flores, Juan Arturo; Faundez-Zanuy, Marcos; de la Cueva, Victor; Mekyska, Jiri (IEEE Access. 2021 Oct 22;(9):141599-141610, 2021-10-22)
      Parkinson’s disease (PD) is the second most frequent neurodegenerative disease associated with several motor symptoms, including alterations in handwriting, also known as PD dysgraphia. Several computerized ...
    • Handwriting biometrics: applications and future trends in e-security and e-health 

      Faundez-Zanuy, Marcos; Fierrez, Julian; Ferrer, Miguel A; Diaz, Moises; Tolosana, Ruben; Plamondon, Réjean (Cognitive Computation. 2020;12;940–953, 2020)
      Online handwritten analysis presents many applications in e-security, signature biometrics being the most popular but not the only one. Handwriting analysis also has an important set of applications in ...
    • Identification and monitoring of Parkinson’s disease dysgraphia based on fractional-order derivatives of online handwriting 

      Mucha, Ján; Mekyska, Jiri; Galaz, Zoltan; Faundez-Zanuy, Marcos; López-de-Ipiña, Karmele; Zvoncak, Vojtech; Kiska, Tomáš; Smekal, Zdenek; Brabenec, Lubos; Rektorova, Irena (Applied Sciences. 2018;8(12):2566, 2018-12-11)
      Parkinson’s disease dysgraphia affects the majority of Parkinson’s disease (PD) patients and is the result of handwriting abnormalities mainly caused by motor dysfunctions. Several effective approaches ...
    • Mood state detection in handwritten tasks using PCA–mFCBF and automated machine learning 

      Nolazco Flores, Juan Arturo; Faundez-Zanuy, Marcos; Velázquez-Flores, O. A.; Del-Valle-Soto, Carolina; Cordasco, Gennaro; Esposito, Anna (Sensors. 2022 Feb 21;22(4):1686, 2022 Feb 2)
      In this research, we analyse data obtained from sensors when a user handwrites or draws on a tablet to detect whether the user is in a specific mood state. First, we calculated the features based on the ...
    • On handwriting pressure normalization for interoperability of different acquisition stylus 

      Faundez-Zanuy, Marcos; Brotons-Rufes, Olga; Paul Recarens, Carles; Plamondon, Réjean (IEEE Access. 2021 Jan 21;9:18443-18453, 2021-01-21)
      In this paper, we present a pressure characterization and normalization procedure for online handwritten acquisition. Normalization process has been tested in biometric recognition experiments (identification ...
    • On the analysis of speech and disfluencies for automatic detection of Mild Cognitive Impairment 

      López-de-Ipiña, Karmele; Martinez de lizarduy, Unai; Calvo, Paula M.; Beitia, Blanca; García Melero, J.; Fernández, E.; Ecay-Torres, Mirian; Faundez-Zanuy, Marcos; Sanz, P. (Neural Computing and Applications. 2020;32:15761–15769, 2018-05-08)
      Alzheimer’s disease is characterized by a progressive and irreversible cognitive deterioration. In a previous stage, the so-called Mild Cognitive Impairment or cognitive loss appears. Nevertheless, this ...
    • Quantitative analysis of relationship between hypokinetic dysarthria and the freezing of gait in Parkinson’s disease 

      Mekyska, Jiri; Galaz, Zoltan; Kiska, Tomas; Zvoncak, Vojtech; Mucha, Jan; Smekal, Zdenek; Eliasova, Ilona; Kostalova, Milena; Mrackova, Martina; Fiedorova, Dagmar; Faundez-Zanuy, Marcos; Solé-Casals, Jordi; Gómez Vilda, Pedro; Rektorova, Irena (Cognitive Computation. 2018;10(6):1006-1018, 2018)
      Hypokinetic dysarthria (HD) and freezing of gait (FOG) are both axial symptoms that occur in patients with Parkinson’s disease (PD). It is assumed they have some common pathophysiological mechanisms and ...
    • Reliability and validity of the Polar V800 sports watch for estimating vertical jump height 

      Garnacho-Castaño, Manu; Faundez-Zanuy, Marcos; Serra Paya, Noemi; Maté-Muñoz, José Luis; López Xarbau, Josep; VILA BLANCH, MOISÈS (Journal of Sports Science and Medicine. 2021;(20):149-157, 2021)
      This study aimed to assess the reliability and validity of the Polar V800 to measure vertical jump height. Twenty-two physically active healthy men (age: 22.89 ± 4.23 years; body mass: 70.74 ± 8.04 kg; ...
