Clasificación de hiperintensidades presentes en la sustancia blanca en imágenes de resonancia magnática usando extracción de características y redes neuronales

In this work, a model to classify lesions present in white matter is shown, using as classifier a Back-Propagation Multilayer Neural Network (BPMNN), which is fed by a featured vector, whose properties derived from the feature extraction of histogram and texture analysis of magnetic resonance images; given that a supervised learning with previous knowledge is used, it is important to label the ...

Mejora de Contraste y Compensación en Cambios de la Iluminación

In this paper a contrast operator built by means of two primitives involving Weber’s Law is presented. The proposed contrast mapping has two objectives, in the first place the contrast enhancement and in the second, the normalization of the processed image. The contrast enhancement is based on the image background detection; this parameter is computed through the analysis of the regional minimu...
