Detection of microcalcifications in mammograms using error of prediction and statistical measures
(Society of Photo-optical Instrumentation Engineers, 2009)
A two-stage method for detecting microcalcifications in mammograms is presented. In the first stage, the determination of the candidates for microcalcifications is performed. For this purpose, a 2-D linear prediction ...

Simulation of nonlinear distortion in W-CDMA communication circuits
(Society of Photo-optical Instrumentation Engineers (SPIE), 2004-04)
Different circuit-level approaches to study the effects of nonlinear distortion on coded division multiple access (CDMA) wireless communication systems are analyzed. These techniques are used to predict spectral regrowth ...

Clasificación de lesiones de piel basada en filtros de Gabor y color
(Sociedad española de ingeniería biomédica, 2009)
Cuando se pretende diagnosticar un posible cáncer de piel, los médicos evalúan la lesión siguiendo diferentes reglas. Aunque la más famosa es la regla ABCD (Asimetría, Borde, Color, Diámetro), una técnica muy empleada ...

Combining blind source extraction with joint approximate diagonalization: Thin algorithms for ICA
(2003)
In this paper a multivariate contrast function is proposed for the blind signal extraction of a subset of the indepen dent components from a linear mixture. This contrast com bines the robustness of the joint approximate ...

Maximal Contrast Adaptive Region Growing for CT Airway Tree Segmentation
(CreateSpace Independent Publishing Platform, 2009)
In this paper we propose a fully self-assessed adaptive region growing airway segmentation algorithm. We rely on a standardized and self-assessed region-based approach to deal with varying imaging conditions. Initialization ...

Colorimetric calibration of images captured under unknown illuminants
(AIC, 2009)
In this paper the problem of acquiring colorimetrically-calibrated images under multiple uncontrolled illuminants is studied. One of the main applications is diagnosis of different injuries by skin colour analysis, these ...

Perceptual color clustering for color image segmentation based on CIEDE2000 color distance
(2009)
In this paper, a novel technique for color clustering with application to color image segmentation is presented. Clustering is performed by applying the k-means algorithm in the L*a*b* color space. Nevertheless, Euclidean ...

Color analysis of the reconstructed complex nipple-areola after a mastectomy
(2009)
In this paper a colour analysis of the reconstructed NAC (nipple-areola complex) after a mastectomy is performed. First, a colour segmentation algorithm based on the Live Wire method is proposed to separate the NAC from ...
