The events of the past 2 years related to the pandemic have shown that it is increasingly important to find new tools to help mental health experts in diagnosing mood disorders. Le…
Hand Geometry Based Recognition with a MLP Classifier
Marcos Faundez-Zanuy, Miguel A. Ferrer-Ballester, Carlos M. Travieso-González +1
This paper presents a biometric recognition system based on hand geometry. We describe a database specially collected for research purposes, which consists of 50 people and 10 diff…
Face recognition with small and large size databases
Josep roure-Alcobé, Marcos Faundez-Zanuy
This paper presents experimental results using the ORL (40 people) and FERET (994 people) databases. The ORL database can be useful for securing applications where few users attemp…
Biometric verification of humans by means of hand geometry
Marcos Faundez-Zanuy
This paper describes a hand geometry biometric identification system. We have acquired a database of 22 people, 10 acquisitions per person, using a conventional document scanner. W…
Study of a committee of neural networks for biometric hand-geometry recognition
Marcos Faundez-Zanuy
This Paper studies different committees of neural networks for biometric pattern recognition. We use the neural nets as classifiers for identification and verification purposes. We…
Biometric identification by means of hand geometry and a neural net classifier
Marcos Faundez-Zanuy, Guillermo Mar Navarro Mérida
This Paper describes a hand geometry biometric identification system. We have acquired a database of 22 people using a conventional document scanner. The experimental section consi…
Face recognition in a transformed domain
Marcos Faundez-Zanuy
This paper proposes the use of a discrete cosine transform (DCT) instead of the eigenfaces method (Karhunen-Loeve Transform) for biometric identification based on frontal face imag…
Face identification by means of a neural net classifier
Virginia Espinosa-Duro, Marcos Faundez-Zanuy
This paper describes a novel face identification method that combines the eigenfaces theory with the Neural Nets. We use the eigenfaces methodology in order to reduce the dimension…
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…
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…
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…
Preliminary experiments on automatic gender recognition based on online capital letters
Marcos Faundez-Zanuy, Enric Sesa-Nogueras
In this paper we present some experiments to automatically classify online handwritten text based on capital letters. Although handwritten text is not as discriminative as face or…
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…
