Color-texture image segmentation based on multistep region growing
(Society of Photo-optical Instrumentation Engineers, 2006)
A new method for color image segmentation is proposed. It is based on a novel region-growing technique with a growth tolerance parameter that changes with step size, which depends on the variance of the actual grown ...

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 ...

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 ...

Segmentation-based lossless compression of burn wound images
(Society of Photo-optical Instrumentation Engineers, 2001)
Color images may be encoded by using a gray-scale image compression technique on each of the three color planes. Such an approach, however, does not take advantage of the correlation existing between the color planes. ...

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 ...

Detección Automática de Microaneurismas en Retinografías para Diagnóstico Precoz de Retinopatía Diabética
(Sociedad Española de Ingeniería Biomédica, 2009)
En este trabajo presentamos un prototipo de herramienta de detección automática de microaneurismas (MA) en retinografías en color. Este algoritmo evoluciona a partir de trabajos anteriores como la detección de ...
