The purpose of the study was to evaluate brain myelination by measuring the magnetization transfer ratio (MTR) and to measure grey (GMV) and white matter volume (WMV) in macrocephalic children with neurofibromatosis type 1 (NF1). Seven NF1 patients (aged 0.65–16.67 years) and seven age- and gender-matched controls were studied. A three-dimensional (3D)(More)

A diagnostic system is presented that employs morphometry combined with a fuzzy neural network approach, for the discrimination of benign from malignant gastric lesions. The input to the system consists of images of routine processed gastric smears stained by Papanicolaou technique. The analysis of the images provides a data set of cell features. The fuzzy(More)
A neural network classiier using fuzzy set representation of pattern classes is presented. Network construction and learning is performed incrementally in a single pass by building an aggregate of space-lling regions that constitutes a simpliied variant of the construction known as Dirichlet tesselation (or Voronoi diagram). Each region is delimited by a(More)
A computer program named TRIAC II written in MATLAB and running with a friendly GUI has been developed for recognition and parameters measurements of particles’ tracks from images of Solid State Nuclear Track Detectors. The program, using image analysis tools, counts the number of tracks and depending on the current working mode classifies them according to(More)
In this study the classification of B-scan ultrasonic liver images using a novel fuzzy neural network classifier is investigated. Image texture analysis techniques were used to extract classification features. The techniques used are the Fractal Dimension Texture Analysis (FDTA), the Spatial Gray Level Dependence Matrices (SGLDM), the Gray Level Difference(More)
The fuzzy min-max classiication network constitutes a promisimg pattern recognition approach that is based on hy-berbox fuzzy sets and can be incrementally trained requiring only one pass through the training set. The deenition and operation of the model considers only attributes assuming continuous values. Therefore, the application of the fuzzy min-max(More)
