Abstract

PARTIENDO DE UN PIXEL NEGRO DE CONSTRUCCION DE IMAGEN QUE HA SIDO DETECTADO EN UNA MUESTRA (PI) DE IMAGEN DE CODIFICACION BINARIA, DISPONIENDO LOS ALREDEDORES DEL PIXEL NEGRO DE UN NUMERO REDUCIDO DE PIXELS VECINOS SE CHEQUEA CON RESPECTO A OTROS PIXELS NEGROS. EL TAMAÑO REAL ASI DETERMINADO DE LA ZONA DE CONTINUIDAD (P.EJ. CC1) FORMADA POR TODOS LOS PIXELS NEGROS DETECTADOS ES COMPARADA CON RESPECTO A UN TAMAÑO MAXIMO PREDETERMINABLE. SI EL TAMAÑO REAL ES MENOR QUE EL TAMAÑO MAXIMO, SE SELECCIONA UN NUMERO INCREMENTADO DE PIXELS VECINOS, CON RESPECTO AL NUMERO SELECCIONADO PREVIAMENTE, Y LOS ALREDEDORES DE CADA PIXEL PERTENECIENTE A LA ZONA DE CONTINUIDAD YA FORMADA (P. EJ. CC1) SE CHEQUEA CON RESPECTO A PIXELS NEGROS ADICIONALES SOBRE LA BASE DEL NUMERO INCREMENTADO MENCIONADO DE PIXELS VECINOS.
