In this paper an approach to detect smoke columns from outdoor forest video sequences is proposed. The approach follows three basic steps. The first step is an image preprocessing block which resizes the image by applying a bicubic interpolation algorithm. The image is then transformed to its intensity values with a gray-scale transformation and finally the(More)
In this paper we propose an approach to detect microcalcifications in digital mammograms using the dual-tree complex wavelet transform (DT-CWT).The approach follows four basic strategies, namely, image denoising, band suppression, morphological transformation and inverse complex wavelet transform. Recently, the DT-CWT has shown a good performance in(More)
This paper presents an application-based model for classifying and identifying attacks in a communications network and therefore guarantees its safety from HTTP protocol-based malicious commands. The proposed model is based on a recurrent neural network architecture and it is therefore suitable to work online and for analyzing non-linear patterns in real(More)
The design and construction of two Metamaterial (MTM) directional filters (DF) for multiplexing applications at 900 MHz is presented. The four-port filters are realized using composite-right-left-handed (CRLH) closed-loop resonators, which present small dimensions and suppression of harmonic resonances due to the zeroth-order resonance produced by MTM’s.(More)
In this paper we present a fuzzy reasoning model and a designed system for Recognition of Facial Expressions, which can measure and recognize the intensity of basic or non-prototypical emotions. The proposed model operates with encoded facial deformations described in terms of either Ekman ́s Action Units (AUs) or Facial Animation Parameters (FAPs) of(More)
This paper deals with the experimental transmission of analog TV-signal in a fiber-radio scheme using a microwave photonic filter. For that purpose, filtering of a microwave band-pass window located at 2.8GHz is obtained by the interaction of an externally modulated multimode laser diode emitting at 1.5μm associated to the chromatic dispersion parameter of(More)
In the area of digital image processing, active models or snakes are mainly used for detection of object contours such as those in AFM images (Atomic Force Microscope), with certain characteristics defined by the user using prior knowledge. This information is utilized for object segmentation, object tracking, object recognition and other tasks. In this(More)
