[EN] In this paper, we introduce a hybrid real-time
method for vision-based pedestrian detection
made up by the sequential combination of two
basic methods applied in a coarse to fine fashion.
The proposed method aims ...

[EN] In this paper, a new model for processing colour images is presented. A graph is built for each image pixel taking into account some constraints on links. Each pixel is characterized depending on the features of its ...
[EN] Occupancy grid maps have been widely used in robotics for navigation assistance. Most of the current occupancy maps use grids based on Cartesian coordinates. In this paper, we introduce a new approach to occupancy map ...

[EN] The sequential p-convergence in a fuzzy metric space, in the sense of George and Veeramani, was introduced by D. Mihet as a weaker concept than convergence. Here we introduce a stronger concept called s-convergence, ...
In the context of fuzzy metrics in the sense of George and Veeramani, we study
when certain families of open balls centered at a point are local bases at this point.
This question is related to p-convergence and ...

Mixed impulsive and Gaussian noise reduction from digital color images is a challenging task because it is necessary to appropriately process both types of noise that in turn need to be distinguished from the original image ...
[EN] This paper describes a new filter for impulse noise reduction in colour images which is aimed at improving the noise reduction capability of the classical vector median filter. The filter is inspired by the application ...

Neuroblastoma is a childhood cancer with a high mortality. To detect it, a gammagraphy scan is done, injecting prior to it a radioactive isotope, the iodobenzylguanidine (MIBG), to the patient. MIBG reacts with the cancer, ...
[EN] In this paper we survey some concepts of convergence and Cauchyness appeared separately in the context of fuzzy metric spaces in the sense of George and Veeramani. For each convergence (Cauchyness) concept we find a ...

[EN] In this work we introduce a practical case application of approximations of function and definite integral to approach a problem in civil and building engineering. The objective is to approximate the volume involved ...
In this paper we give a characterization of the class of completable strong (non-Archimedean) fuzzy metric spaces, in the sense of George and Veeramani.

Las imágenes digitales se ven afectadas por la inclusión de ruido
tanto durante el proceso de adquisición como en los procesos de
transmisión y almacenamiento. Este ruido presente en las imágenes
puede suponer un grave ...
