In biological vision systems, the attention mechanism is responsible for selecting the relevant information from the sensed field of view. In robotics, this ability is specially useful because of the restrictions in ...

This paper presents a new segmentation technique for color images. It relies on building an irregular pyramid into a regular one, presenting only nodes associated to homogeneous color regions. Hence, the size of the irregular ...

El análisis facial es uno de los procesos claves para las interacciones humanas en la vida diaria. La gente es capaz de inferir el género, la edad, las emociones, etc. desde una única imagen de un rostro humano. También ...

Combinatorial pyramids represent the image as a stack of successively reduced combi- natorial maps, which encode the whole image at different levels of abstraction. Within this framework, this paper proposes to conduct ...

There exist image processing applications, such as tracking or pattern recognition, that are not necessarily precise enough to maintain the same resolution across the whole image sensor. In fact, they must only keep it as ...

Este Trabajo Fin de Grado se enfoca en la técnica de la fotopletismografía de imagen (iPPG) y su aplicación en la telemedicina. La iPPG es una técnica no invasiva que utiliza cámaras o sensores ópticos para medir los cambios ...

Towards developing an interface for human–robot interaction, this paper proposes a two-level approach to recognise gestures which are composed of trajectories followed by different body parts. In a first level, individual ...

This Ph.D. Thesis presents a novel part-based approach for automatic object detection in real scenes. For that purpose, the scene is represented using a novel perceptual segmentation approach, also presented in this thesis, ...

Artificial vision systems can not process all the information that they receive from the world in real time because it is highly expensive and inefficient in terms of computational cost. However, inspired by biological ...
