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…
Graphomotor and Handwriting Disabilities Rating Scale (GHDRS):towards complex and objective assessment
Jiri Mekyska, Katarina Safarova, Tomas Urbanek +10
Graphomotor and handwriting disabilities (GD and HD, respectively) could significantly reduce children's quality of life. Effective remediation depends on proper diagnosis; however…
Preliminary experiments on thermal emissivity adjustment for face images
Marcos Faundez-Zanuy, Xavier Font Aragones, Jiri Mekyska
In this paper we summarize several applications based on thermal imaging. We emphasize the importance of emissivity adjustment for a proper temperature measurement. A new set of fa…
Contribution of the Temperature of the Objects to the Problem of Thermal Imaging Focusing
Virginia Espinosa-Duró, Marcos Faundez-Zanuy, Jiri Mekyska
When focusing an image, depth of field, aperture and distance from the camera to the object, must be taking into account, both, in visible and in infrared spectrum. Our experiments…
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…
Face segmentation: A comparison between visible and thermal images
Jiri Mekyska, Virginia Espinosa-Duró, Marcos Faundez-Zanuy
Face segmentation is a first step for face biometric systems. In this paper we present a face segmentation algorithm for thermographic images. This algorithm is compared with the c…
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 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…
A comparative study of in-air trajectories at short and long distances in online handwriting
Carlos Alonso-Martinez, Marcos Faundez-Zanuy, Jiri Mekyska
Introduction Existing literature about online handwriting analysis to support pathology diagnosis has taken advantage of in-air trajectories. A similar situation occurred in biomet…
Thermal hand image segmentation for biometric recognition
Xavier Font-Aragones, Marcos Faundez-Zanuy, Jiri Mekyska
In this paper we present a method to identify people by means of thermal (TH) and visible (VIS) hand images acquired simultaneously with a TESTO 882-3 camera. In addition, we also…
