Abstract

EL PROCESO DE COMPRESION DE IMAGENES CONSISTE EN TRATAR UN BLOQUE PIXELS CORRIENTE DESPLAZADO EN LA IMAGEN A COMPRIMIR UTILIZANDO UNA RED DE N NEURONAS, 1 A N, DISPUESTOS EN UN MISMO PLANO, TENIENDO CADA NEURONA UN NUMERO DE ENTRADAS IGUAL A LA DIMENSION DE LOS BLOQUES EXTRAIDOS DE LA IMAGEN, Y DE TAL MANERA QUE, DESPUES DE UNA FASE DE APRENDIZAJE DURANTE LA CUAL LA RED SE AUTOORGANIZA, DE MANERA QUE LAS NEURONAS REPRESENTAN LOS VALORES DE ENTRADA MAS PROBABLES, CADA NEURONA RECIBE, EN EL MISMO INSTANTE, SOBRE SUS ENTRADAS LOS PIXELS DEL BLOQUE CORRIENTE Y EMITE EN LA SALIDA UNA SEÑAL, O POTENCIAL, DJ QUE ES POSITIVO Y POR CONSIGUIENTE MAS DEBIL QUE EL ESTADO DE LA NEURONA J CORRESPONDIENTE CERCANA AL ESTADO DE LAS ENTRADAS EI, EN CODIFICAR EL BLOQUE DE PIXELS CORRIENTE POR UN CODIGO ASOCIADO A LA NEURONA J CUYO POTENCIAL DJ ES MINIMO. LA INVENCION SE APLICA, EN PARTICULAR, EN LA COMPRESION DE IMAGENES DE TELEVISION.
