Esta tesis presenta dos sistemas implementados mediante técnicas de procesamiento de imagen, para ayuda al diagnóstico de enfermedades neuromusculares a partir de imágenes de microscopía de fluorescencia y análisis de lesiones pigmentadas a partir de imágenes dermoscópicas. El diagnóstico de enfermedades neuromusculares se basa en la evaluación...

In this paper a model-based method of classificationof global patterns in dermoscopic images is proposed. Global patterns identification is included in the pattern analysisframework, the melanoma diagnosis method most used amongdermatologists. The modelling is performed in two senses: first adermoscopic image is modelled by a finite symmetric...

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 images would be captured in hospitals where lighting conditions are uncontrolled. To gain some control over illumination, a...

Morphogenesis is consequence of lots of small coordinated variations that occur during development. In proliferating stages, tissue growth is coupled to changes in shape and organization. A number of studies have analyzed the topological properties of proliferating epithelia using the Drosophila wing disc as a model. These works are based in...

In this study a set of colour gradients based on colour visual perception, which use International Commission on Illumination (CIE) L*a*b* colour space, is presented. The main objective is the study of how the colour difference equations, developed by CIE, affect the estimation of the gradients in terms of correlation with colour visual...

Natural packed tissues are assembled as tessellations of polygonal cells. These include skeletal muscles and epithelial sheets. Skeletal muscles appear as a mosaic composed of two different types of cells: the "slow" and "fast" fibres. Their relative distribution is important for the muscle function but little is known about how the fibre...

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 the rest of skin. And then the colour differences between the healthy and the reconstructed NAC are measured using...

La segmentación del Disco Óptico (DO) es un paso esencial para la extracción automática de estructuras anatómicas y lesiones retinianas. La mayoría de los algoritmos de segmentación de la literatura procesan exclusivamente un solo plano de la retinografía, descartando la información de color. En este artículo se presenta un nuevo algoritmo...

Diagnosis of neuromuscular diseases is based on subjective visual assessment of biopsies from patients by the pathologist specialist. A system for objective analysis and classification of muscular dystrophies and neurogenic atrophies through muscle biopsy images of fluorescence microscopy is presented. The procedure starts with an accurate...
